[try 6][Gdiplus 01/10] Implement GdipGetRegionData

[Adam Petaccia]

Changelog:
(try6):
    Use DWORD as the base type in write_element to avoid some casts
    Use another helper function to write pathtypes, and avoid an overzealous ZeroMemory
    Don't hardcode 4 when we mean sizeof(DWORD) or even something else.
    Add documentation, as MSDN isn't helpful on this at all.

(try4):
    region->node is no longer a pointer
    Apply const qualifier to helper function
(try2):
    We might not write a whole DWORD for pathflags, so make sure its not
    garbage; revealed by the added test at the end of this series.
