The CPU fallback of the compute renderer needs ReadPixels data in OpenGL format (origin at bottom left). Unfortunately, the OpenGL driver automatically mirrors images in the Y-axis to match the top left origin image.RGBA. Remove the mirroring from the driver and introduce a DownloadImage to restore the old behaviour. Signed-off-by: Elias Naur <mail@eliasnaur.com>
