Just in case some applications depend on it. So far noone cared, at least
regarding bug reports.

Current GdipCreateRegionRgnData implementation fully supports data
generated by GdipGetRegionData, and I don't have an intention to
pollute the code with useless FIXMEs. If you have an application
that doesn't work with my implementation then just file a bug report
and I'll have a look.
