I've no particular objections. They didn't get into 5-1 because I was
still working on them at 5-1 branch time and they needed more time to
get through new bugs/improvements they might need.

if you backport, keep an eye out for what the "final form" is in 5-1 vs
5-2/master cause I think there was one or two more tweaks to the alpha
mask stuff.
