What is really missing for me here is being able to select which area
from the source Context will be copyed. Any ideas?

CGImageRef original = CGBitmapContextCreateImage(context);
CGImageRef subsection = CGImageCreateWithImageInRect(original, subrect);
CGImageRelease(original);
// draw with subsection
CGImageRelease(subsection);
