The contents of the framebuffer are exactly what you see onscreen.  I don't
understand what is 'poor' about the image being read back.

pix_record on OSX is extremely well tested.  I've recorded in excess of one
million files with it.

pix_write should just write the pix buffer to a file and not also have
pix_snap functionality embedded in it.  Unfortunately doing this would break
a lot of patches.  Maybe pix_image_write would be an acceptable option.
