I don't remember seeing these specifically addressed so I figured I'd
ask so I can make sure I'm doing everything correctly. I'm currently
interested in the software rendering case, but if there some
differences in the hardware case, that'd be nice to know as well.
1. So far all the images or video I load into a project for testing
use 32-bit ARGB/RGBA for the pixel format. If I've read the docs
correctly, I should also expect to see 128-bit floating point ARGB/
RGBA pixels in some circumstances. If that's so, what can I do to get
that to happen so I can test that I'm handling that case correctly?
2. Can I assume that the input and output images will always have the
same sized pixels, i.e., I shouldn't expect to see a 32-bit pixel in
the input image(s) and a 128-bit pixel in the output image?
