annotate Small_CPU/Src/scheduler.c @ 868:db92692c014f Evo_2_23
Introduce speed dependend coloring of depth:
The depth value in the will now be colored based on the current ascent speed. The color code matches the one of the bar graph which was already used for visualization of the ascent speed. To keep color code consistent the existing color selection functions have been merged to one common Gfx function (T3/T7 - bar graph and color text)
