Graphics/Image: dont store PixelFormat, instead define a new enum for number of channels.

Browse source 
The image class has a strict internal representation so we dont need "format".
PixelFormat enum can be passed to functions that modify the pixel data (like setPixels()) so that a proper convertion can be done.
