The problem I was having with those was that many of those use IntRects. The desired result
for the Inspector code was a FloatQuad. IntRects for instance cannot be used for rotated content.
I think I can switch to the functions you mention above, if there a way that I can then apply all
the transforms that would affect that resulting IntRect. Do you know offhand if there is an
existing way to do that?
