Comment (by pulkomandy):

 This could be implemented at the video driver level (by changing video
 card gamma correction tables). Failing this, I guess we could attempt
 doing it at app_server level but I can sense problems coming:
 - With apps doing drawing on their own,
 - With apps asking app_server to draw something and then reading back from
 it or doing any kind of post-processing

 So it could be done when copying the data to the screen frontbuffer, at
 best. And usin the hardware would be better but needs drivers to
 collaborate (which probably means no support in VESA driver then)
