[suggestion] Visually represent note Volume with color saturation

[huderlem]

In DAWs, it's standard practice to represent note Volume/Velocity with a color spectrum. I think it's usually light blue -> red, from soft to loud. Since Crystal Tracker uses note color to denote each of the 4 channels, it could represent softer notes as less saturated, or something similar to that. Currently, the magenta bar indicates that a volume change occurred, but it would be nice if that was visually recognizable at a glance based on the note's color.

Yeah, getting more information at-a-glance about volume envelope specifically would be great. Varying the note color is an interesting idea. I'll keep brainstorming on this.
