[PATCH] gdiplus: Support GdipSetClipRegion in metafiles

[Vincent Povirk]

+    stat = GdipGetRegionData(region, (BYTE*)object_record +
FIELD_OFFSET(EmfPlusObject, Header.Size), size, NULL);
+    object_record->Header.DataSize = object_record->Header.Size;
+    object_record->Header.Size = record_size;

This is a little too clever. I'd rather have a solution similar to
write_path_data.
