[Caio S. Souza]

QT deals with color information. Or better, on how QT doesn't do any
color transformation.

I know Krita. It's a great software! I completely forgot it was
written with QT. I'll take a look on how you display the processed
pixels. Could point me a start point at Krita's source code?

That's really cool!
