src/giza.h: Add support for PG[SQ]ITF, fix PGCONT PGPLOT has three image transfer functions defined for PGIMAG:
linear, log, sqrt. These are now implemented by this commit. The current render engine uses pixel-colour-indices to colour
pixels: based on the pixel value, limits, the transfer function
computes the "position" of the pixel on the 0->1 scale and
transforms that to the nearest colour index from the current
CIMIN/CIMAX colour index range. (To follow PGPLOT docs.) The old code would ignore the colour index range and for each pixel
interpolate the colour table that was set, basically always "true
colour" representation. In a subsequent commit I could provide
infrastructure to support both: code calling giza_render() directly
would return to this behaviour, the call via the PGPLOT interface
would force it through using colour index range. The code now has several flavours of transforming a pixel value to a
normalized colour (on the interval 0..1) or converting that directly
into a colour index between cimin, cimax. In the process fixed some minor bugs. Tested using pgdemo4, adding a PGSITF([123]) manually in the demo
program.

* src/giza-colour-table.c: Fix giza_set_colour_table to set
colourindices The function would warn about inconsistent entries in the
controlPoints and return with an error, not setting the colour-index
table. PGPLOT pgdemo4 (demonstrating PGIMAG) has a table with controlpoints
outside the range 0->1 (-.5, 1.7) triggering this warning and error
exit. The colour table is installed nonetheless! Net effect: pixel
colourings in "true colour" - i.e. those that do not go through
colour indices - keep on working, but those relying on colour
indices don't. This fix prints the warning, checks that a sensible number of
control points remain, and then goes on computing the colours for
the set colour index range (PGSCIR) - as per documentation.

https://sites.astro.caltech.edu/~tjp/pgplot/subroutines.html#PGPT). Using the pgdemo2 program, 2nd page (SUBROUTINE PGEX22 in
pgdemo2.f), this behaviour can be tested. I modified both the
linewidth (LW=8) and the character height (CH=2.5) to see how PGPLOT
handles this. Indeed PGPLOT makes the symbols larger and draws thicker lines. The
Giza master branch does not follow this behaviour. This commit seeks
to address that. Some base symbols had to be scaled up a bit wrt to their current
setting, after which character height scaling could be used to do
the rest. giza-points.c does not set a fixed line width anymore, in stead it
follows the current device's setting.

* src/giza-driver-xw.c, src/giza-drivers.c: Synchronize XW device id
with giza_device_t The global variable 'id' is now also used to address the instance of
the GIZA_XWindow struct where giza_device_t Dev[id]'s properties are
stored. This can be done because: - giza-driver-xw.c implements a shadow array, "XW", of euqal length
as the Dev[...] array (GIZA_MAX_DEVICES - `giza_open_...()` now searches for an unused entry in Dev[...]
when opening a device - `giza_close_device()` closes the correct device when it's, well,
closed. If the entry happened to be an XWindow, the corresponding
XW[id] struct will now also be properly closed.

src/giza-driver-xw.c: Fix device specific close fn's giza_open() now detects and handles errors occuring during setup of
the new device. The device specific _giza_close_<device>() functions
needed to be updated to deal with partially/not fully initialized
devices. For the XWindow driver, its shadow administration of GIZA_XWindow
devices (the "XW[...]" array) needed to be managed slightly
different, not unlinke how devices are now
initialized/de-initialized in giza-drivers.c The global 'xid' variable was removed and replaced by a lookup in
the (already existing) giza_xw_id[...] table. Thinking about it, it seems to me the whole shadow 'xid'
administration can be simplified if Dev[N], if Dev[N] refers to an
XWindow, stores its peculiars in XW[N]. `giza_open()` now already
takes care of finding an empty slot and there should be no reason
for the XWindow driver to use that assigned slot as well. A separate commit implementing that will follow, which makes that
change opt-in.

* src/giza-drivers.c, src/giza-private.h,
src/giza-set-font-private.h, src/giza-set-font.c, src/giza.h: Font
memory management changed In order to (1) prevent excessive font unload/load sequences and (2)
proper support for per-device font handling and (3) simplifying font
loading and (4) get a handle on memory management, the giza_set_font()
implementation was changed. Fonts are now cached internally based on the primary key
(font-family, slant, weight) and reference counted across open
devices. Up to three mechanisms of loading a font are tried: FreeType,
FontConfig and cairo_toy_font - depending on cairo version and
wether cairo was compiled with support for that. FreeType/FontConfig
library initialization code made more robust and handling error(s)
and releasing allocated memory in such a case was improved. Extra code to ensure cache unloading at program end was added.

* src/giza-box.c, src/giza-cpgplot.c, src/giza-format-number.c,
src/giza-fortran.F90, src/giza.h: `giza_format_number()` string
buffer length The `giza_format_number()` function writes unconditionally to a
destination string buffer without being informed how large that
buffer is. This commit adds an extra parameter to be passed to
`giza_format_number()` - the size of the string buffer. It changes
the implementation to take care of not writing outside the
destination string's boundaries. It should be noted that this may have an effect on
cpgnumb()/PGNUMB() because there is no officially documented
necessity that the *string_length parameter in cpgnumb() has to
contain the size of the buffer upon entry; the documentation only
mentions the contents of that parameter are set on output to the
number of characters written. I have checked the official PGPLOT libcpgplot binding and
perl5-PGPLOT which both do this: both write the size of the FORTRAN
string in the parameter before calling cpgnumb() or use a temporary
variable and pass that size in. I have updated giza-fortran.F90 to
do the same. The Python-PGPLOT binding (ppgplot) does not expose cpgnumb() so at this point that's not an
issue.

* src/giza-cpgplot.c, src/giza-drivers.c, src/giza.h: Fix multi dev
handling (SIGSEGV, libc corruption) The giza library, specifically in `giza_open_device_size()` and
`giza_close_device()`, did not handle multiple devices being opened
and closed in random order - which is what my own application
happens to do. The internal bookkeeping got out of sync with the user's device
identification, leading to API calls wreaking havoc because they
would apply to an unitialized giza_device_t entry or overwrite
properties of a giza_device_t they weren't supposed to. (E.g.
cpgopen() could easily overwrite an already open device entry,
cpgclos() could fail because the internal bookkeeping had forgotten
that the user's open device actually existed). Long story short: SIGSEGV and program termination because libc
malloc had detected corruption of its internal structures ensued. In order to fix this a slightly larger than normal edit had to take
place. Entries in the global giza_device_t array are now properly
initialized and de-initialized to a known state, even when opening a
device fails halfway through. PGEND() / cpgend() did not, contrary to documentation, close all
current open devices; now it does.

* src/giza-points.c: Fix symbols 12, 18 (5-pt star), #20 initiated Symbols 12 and 18 now are five-point stars, open and filled. Symbol
20 was entered as seven-point star but it should be a small open
circle. Already changed it from _giza_star() => _giza_circle() but
symbols 20-27 are a bit off anyway, so that's going to be fixed in a
different commit.

* : Merge pull request #3 from haavee/master giza_parse_string() fix, add cpgqinf() support, fix critical bug
found doing this
2018-09-06 Harro Verkouter <hverkouter@gmail.com>
* src/giza-cpgplot.c, src/giza-drivers-private.h,
src/giza-drivers.c, src/giza-fortran.F90, src/giza.h: Support
cpgqinf(), fix critical bug Found out that the fortron giza pgplot binding implemented PQQINF()
(to query version &cet) but the C-language binding didn't. Whilst implementing cpgqinf() found that giza_query_device() and
_giza_int_to_device() contained a serious bug, with SIGSEGV looming
or loss of information. Both quoted functions copy information into a user allocated string
buffer. Extract of relevant code with 'noise' deleted: _giza_int_to_device (int numDevice, char *DeviceName) { case GIZA_DEVICE_NULL: strncpy(DeviceName, "/null", sizeof(DeviceName)-1); break; .... The user allocated buffers are passed by pointer ("char*
DeviceName") and the 'sizeof(...)' operator returns the size of the
_pointer_ not the size of the buffer it's pointing at! Depending on the platform "sizeof(char*) - 1" evaluates to 3 (32
bit) or 7 (64 bit), irrespective of how many characters the user
really allocated. This can lead to either: - overestimating the amount of characters available in case the
user allocated less than 3 (or 7) bytes for their buffer. A
strncpy() with a source longer than 3 (or 7) would then overwrite
memory that it shouldn't, which in turn would lead to unpredictable
behaviour at best and program termination via SIGSEGV at worst. - underestimating the amount characters available if the user
allocated more than 3 (or 7) characters for their target buffer.
In this case, the strncpy() with a source string > 3 (or 7)
characters would truncate the output - e.g. the file name of a
device would easily be > 7 characters long but at most 3 (or 7) of
them would be copied. This would lead to unnecessary loss of
information. In order to fix this the target buffer size must be explicitly
passed to the functions by the caller. Thus the prototype of
giza_query_device() needed to be altered and as a result the Fortran
wrapper needed adapting to the new signature and pass in the extra
variable accordingly.

* src/giza-scanner.l, src/lex.yy.c: Fix backspace handling ... The meaning of the nGlyph index used in giza_parse_string changed
subtly during development and the handling of backspace was not
changed accordingly. The result was that "x^2\b_i" rendered fine but the unit superscript
over the decimal point in PGTBOX() now looked horrible because the
pen position was moved to an erroneous position. Sigh. In order to make "x-i-squared" render nicely it must now be spelled
as: x^2\b\b_i with two backspaces. The first backs up over the
superscript '2', the second backs up over the '^' superscript
operation; when entering the superscript the baseline of the font
and the current pen position is changed immediately. So if that is
not undone before staring to render further characters, the pen
position is not where you hoped it would be.

* src/giza-set-font.c, src/giza.h: giza_set_font_*(...) take const
char* Sometimes compile time static strings are fed into
giza_set_font*(...) calls but their prototype is "char *", implying
mutable strings. None of the functions actually modify their argument so it probably
is better to make this explicit in their prototypes.

* src/giza-driver-xw.c, src/giza-drivers.c: Better XWindow resizing
implementation It turned out that the XWindow resizing wasn't handled correctly in
all cases; notable pgdemo13 (with two x-windows) exposed a problem
in the code in the first window, the one with the choice menu. More often than not it would show ellipses where circles should be
drawn and the text was (way) ouside the window. What happened was two calls to giza_change_page_xw() quickly after
each other. The first had Dev[id].resize = 1 (from PGPAP(...) in
pgdemo13), which triggered an XResizeWindow(...) in the code, to
change the size of the XWindow to the requested device size. The
next call entered with Dev[id].resize = 0 (because that was already
handled) ... but that one detected a window geometry change! Upon
inspection it turned out that, as far as X11 was concerned, the
window still had the /old/ size whilst our internal bookkeeping was
already updated with the requested size. Turns out that the XResizeWindow() does not take effect immediately.
So the code now waits for ConfigureNotify events until the requested
window size has been achieved. Now it works reliably and windows can
be resized between plotting.

* src/giza-io-private.h, src/giza-io.c: Enable formatted
warning/error messages (compat) By changing _giza_warning() and _giza_error() prototype (and
implementation) slightly it is now possible to make the 'message'
parameter be a formatting string (cf. printf("formatting string %s =
%d", s, i)) Now this is possible: _giza_warning("giza_parse_string", "Invalid Hershey number %d",
hershey); _giza_error("giza_parse_string", "Unrecognized token
#%d '%s'", token, yytext); Existing _giza_warning()/_giza_error() calls are completely
unaffected by this.

* src/giza-driver-xw.c: no XWindow resize waiting for keypress Whilst the system is waiting for a keypress, do not honour window
resizing requests. PGPLOT also does not do this.
2018-08-30 Harro Verkouter <hverkouter@gmail.com>
* src/giza-box.c: Fixed earlier broken 'repair' Sometimes the PGPLOT doc is somewhat ambiguous but not for 'N' and
'M' options: both imply labels have to be drawn, only 'M' sais to do
so in the unconvential location. Ambiguity example: does 'L' (logarithmic labelling) *imply* 'N' or
'M' ("write labels")? Or is 'L' only honoured if either 'N' or 'M'
is specified (which is how the code currently works).
2018-08-30 Harro Verkouter <hverkouter@gmail.com>
* src/giza-box.c: Add support for 'M' option to PG(T)BOX When it comes to writing labels PG(T)BOX supports the following: -N :- Label the axis (conventional, below/left viewport) -M :- Put labels in the unconvential location (above/right
viewport) The 'M' option was not implemented by giza so I added it. Whilst at
it removed a few levels of somewhat unnecessary if()'s by adding a
high-level check and sometimes continue'ing from a loop if the rest
of the loop body is precluded from being executed anyway.
2018-08-30 Harro Verkouter <hverkouter@gmail.com>
* src/giza-box-time.c: Fixed minor bugs (logic, off-by-one, missing
/) There were two off-by-one lost-in-FORTRAN-to-C-translation: - using number of items as last accessible index ok in fortran, not so much in C (a classic) - end condition off by one because of pretty much the same in fortran "<" must be <= in C (if C-style counting with fortran meaning of index) I condensed what I thought three levels of fortran IF .. END IF into
a single C "if( x && y && y)" but missed that the 3rd IF was a
single-statement and did not introduce the 3rd 'and' ... IF x THEN IF y THEN IF z <stuff> <other stuff> END IF END IF at first erroneously translated by me into if( x && y && z ) { <stuff> <other stuff> } now reads if( x && y ) { if( z ) <stuff> <other stuff> } And finally in the specification of the super/subscript label
formats I had forgotten to escape the backslash with a backslash in
the strings.

* src/giza-box.c: y-axis ticks on the right were drawn wrong side Obviously the previous edit introduced a sign error :-) If y-axis
ticks were drawn on the right hand side they'd be drawn the same
direction as the ones on the left-hand side. Fixed.
2018-08-30 Harro Verkouter <hverkouter@gmail.com>
* src/giza-box.c: Support for PGBOX 'I' and 'P' options and bug fix giza's pgbox(...) routine did not support the PGPLOT options 'I' and
'P': -I: Invert tick marks - write them outside the viewport in
stead of inside (default) -P: Project major tick marks outside the viewport (ignored if 'I'
also specified) Fixed bug where tickmarks on 'the other side' of the frame were
drawn in the same direction but they need to be inverted: If tick marks on the bottom are drawn inwards (i.e. up) then at the
top they must be drawn downwards to achieve the same effect. The
existing code drew the top tick marks outside the viewport because
it would draw them 'up' as well.
2018-08-30 Harro Verkouter <hverkouter@gmail.com>
* src/giza-box.c: Fix axis ticks not being drawn if axis 'reversed' In checking pgdemo1 certain axes did not display any tick marks at
all! This was traced to be when the window set through pgswin() was
such that Dev[id].Win.[xy]max < Dev[id].Win.[xy]min, i.e. the axis
is reversed: the values decrease towards the right (X) or top (Y)

keeping the original version ... ;-)

* src/giza-box-time.c: Support for pgtbox() The existing pgtbox() redirected to pgbox(). For astronomy application(s) time labelling is very important and a
highly desirable property. The existing PGTBOX() from the PGPLOT source code was ported into an
initial working version, behaving identically, modulo porting bugs.
2018-08-14 Harro Verkouter <hverkouter@gmail.com>
* src/giza-scanner.l, src/lex.yy.c: Support for backspace (\b) in
printing strings For time labelling to look good it is 'necessary' to make the
superscript appear on top of e.g. the decimal point. This can be
done if 'backspace' is supported - backing up the text by one or
more characters. This necessitated rewriting the giza_parse_string() a bit because in
the current version backing up to a previous character's position
was impossible.
