[GR] Better legend marker size scaling

[AdamWysokinski]

Default marker size in the legend is too big for the legend font size.
Reducing scaling by half makes it to scale nicely with :legend_font_pointsize

Could you post some examples? Before vs after?

[AdamWysokinski]

Before:
scatter(rand(100), rand(100), markershape=:o, markersize=2)

scatter(rand(100), rand(100), markershape=:x, markersize=2)

After:
scatter(rand(100), rand(100), markershape=:o, markersize=2)

scatter(rand(100), rand(100), markershape=:x, markersize=2)

Look like this for me:

Is this before or after?

Before, I can't reproduce your results

I think that in your example the marker (while smaller than mine) is still unevenly large for the legend label font size and the plot marker size.

Could you please check this repository: https://notabug.org/AdamWysokinski/DuoMAG
Run the script:

$ ./duomag.jl test.ascii

and compare the output test-butterfly_averaged.pdf with mine (where markers are definitely too large for the legend labels):

How about having some more control over the markersize scaling? Maybe with a keyword 'legend_marker_pointsize'?

Great idea.

Besides possibly adding a keyword to control the markersize in the legend I am very much in favorite of the smaller default markersize (0.8 -> 0.4).
