FS#10935 - Fractals only showing a full black screen with greylib

As the title says, the plugin is currently only drawing a black screen on targets where greylib is used - right from entering the plugin and zooming or moving around changes nothing. This is with revision 24365 but I saw it in slightly older builds too.

I experience this on my OndioFM (monochrome), Iaudio M5 (greyscale) and in an Ipod Mini sim, so it’s fairly safe to assume that it happens on all greylib targets. On my M5 the previous build was new enough that the older mandelbrot.rock still work and it does not have this problem.

Fractals works on my c200 which has a colour screen but I have to admit that I don’t like the new colours much because it’s now a much smaller colour “range”. Of course, that’s not the bug but maybe it has to do with it?

I can confirm this for the Sansa Clip too, it also uses greylib for the fractals plugin.

Confirmed on H100 (r24364), m:robe 100 (r24370) and Mini2G (r24255). Mini2G shows a white screen, all others a black one.

r24309 didn’t had the intended effect: 

  Fractals: this should fix bugs on simulator for greyscale LCD targets.
  * moved #define USEGSLIB to fractal_sets.h and include only needed header file.
  * include plugin.h so that LCD_DEPTH is defined.
  * explicitly include fractal_sets.h in mandelbrot_set.c

bug wasn’t in the sim but in the colors calculation = all colors were 0

And yes color range is weirdly done, I don’t quite get what max_iter really is.
