--- Comment #94 from Tor Lillqvist <[email protected]> ---
How can that work? Surely correspondingly more space must be allocated for the
pRawData in that case, too? The docs for CGBitmapContextCreate say:

data
A pointer to the destination in memory where the drawing is to be rendered. The
size of this memory block should be at least (bytesPerRow*height) bytes.

and the "height" parameter we pass with such a change is nDY * fScale, and
bytesPerRow is (mnBitmapDepth * nDX) / 8, i.e. nDX * 4.
