[PATCH v8 0/4] MR11180: gdiplus: Properly handle raw WMF

[Rose Hellsing (＠axtlos)]

This adds proper raw WMF support commonly used in \\wmetafile RTF documents

It properly fixes the issue [this workaround solves](https://gitlab.winehq.org/mono/wpf/-/merge_requests/13) by adding the missing WMF support in gdiplus.

Tested with the windows wdk installer
