It's too late for that. Public betas are already starting, the only 
things that will go into POV from now until the 3.6 final release are 
bug fixes. The over-allocation fix might get in, but no new features or 
major changes.

Pixels outside that region should probably be fully transparent, to be 
consistent with the "once" option. And why not read in the region as the 
entire image, filling the entire area of the image_map? Simpler, and 
avoids the above problem completely.
