[Mono-dev] Patch to support non-rectangular regions in libgdiplus

[Sebastien Pouliot]

Hello everyone,

Here is the patch to support non-rectangular regions in libgdiplus. All
the existing unit tests pass and valgrind was used to ensure it doesn't
(directly*) leak memory. However my knowledge of Cairo and GDI+ are
fairly recent (and limited) so I won't claim perfection ;-)

The patch is rather large (82K) but, hopefully, it should be easy to
understand. I'll soon commit the test tools I used when developing this
(see the pictures in my recent blog entries) and additional unit tests
for the new features.

* There's one indirect leak (in existing code) that should be fixed
soon.
