Doing all of this at once is really hard to review. I would have preferred to
review each feature removal in a separate patch. However, since this is just
going to be squashed into the DPU megapatch anyways, I guess it's fine.

I only paid close attention to the additions, there are some unrelated
whitespace changes, but also meh on account of the squash (and non seem
objectionable).

What's up with the compiler flag warnings? Seems unrelated (and we should
probably remove all of them in a separate patch anyways).

This goes to 0 and the fg_alpha != 0xff checks are always false. So let's clean
the rest of the function to remove the dead code and variables.
