RFH Enhancement ASCII Only mode

[HansSchulze]

It would be sweet to be able to toggle the HEX part of the dump off and on, to allow viewing more TEXT.
Also, remove the 16 column limit (1000 pixels), with 4K monitors and zoomed out, I can use 4x more width unzoomed, and 8x more zoomed.
With ASCII only unzoomed, 220 pixels at 100% can become >16x wider, or >32x wider zoomed, 256 bytes per line or 512.
Also, if possible, see why zoomed max (2x?) is several hundred ms refresh time if scrolling at full speed past about 32K worth of bytes. It seems to prebuild the scroll window a dozen pages (32 columns full screen 2560x1440 monitor) and scrolls faster than I can read, then drops to slow after that. After a bunch of mouse and keyboard scrolling, the screen updates even slower, leaving streaks of the first line. It seems like there might be a memory leak, given that the performance gets worse over a period of 5 mins.
I'm on Win10/64 Home, GTX2080, 3700X @3.8GHz.
I offer $20 bounty for each.

I've wanted this too, but I never asked because I was concerned I would get too many "booo's" because it's a hex editor. Good for you for having the courage to ask!
