This patch is very incomplete, and probably won't pass the 'make test'.
wine-staging contains a pretty full and well tested patch that reimplements
metafile loading in gdiplus using gdi32 APis:
https://github.com/wine-compholio/wine-staging/blob/master/patches/oleaut32-OLEPictureImpl_SaveAsFile/0001-gdiplus-Reimplement-metafile-loading-using-gdi32-ins.patch
it should be possible to either use it directly or as a base for your work.
There are some other related patches in staging that touch the metafile
loading in gdiplus.
