color blindness enhancement
This is an attempt at improving the experience of
users with color vision impairement.
At this time this feature can only be enabled for
debugging:
adb shell service call SurfaceFlinger 1014 i32 PARAM
with PARAM:
0 : disabled
1 : protanomaly/protanopia simulation
2 : deuteranomaly/deuteranopia simulation
3 : tritanopia/tritanomaly simulation
11, 12, 13: same as above w/ attempted correction/enhancement
The enhancement algorithm tries to spread the "error"
such that tones that would otherwise appear similar can be
distinguished.
