/*****************************************************************************
* GdipGetRegionData [GDIPLUS.@]
*
* Returns the header, followed by combining ops and region elements.
*
* PARAMS
* region [I] region to retrieve from
* buffer [O] buffer to hold the resulting data
* size [I] size of the buffer
* needed [O] (optional) how much data was written
*
* RETURNS
* SUCCESS: Ok
* FAILURE: InvalidParameter
*
* NOTES
* The header contains the size, a checksum, a version string, and the number
* of children. The size does not count itself or the checksum.
* Version is always something like 0xdbc01001 or 0xdbc01002
*
* An element is a RECT, or PATH; Combining ops are stored as their
* CombineMode value. Special regions (infinite, empty) emit just their
* op-code; GpRectFs emit their code followed by their points; GpPaths emit
* their code followed by a second header for the path followed by the actual
* path data. Followed by the flags for each point. The pathheader contains
* the size of the data to follow, a version number again, followed by a count
* of how many points, and any special flags which may apply. 0x4000 means its
* a path of shorts instead of FLOAT.
*
* Combining Ops are stored in reverse order from when they were constructed;
* the output is a tree where the left side combining area is always taken
* first.
