Re: [ros-dev] [ros-diffs] [gadamopoulos] 74457: [UXTHEME] -Use GdiDrawStream in UXTHEME_DrawImageGlyph and UXTHEME_DrawImageBackground.

[Peter Hater]

I know about links, but now Giannis has a little bit more knowledge than original author
and can one up the struct and come up with good constant defines for magics and unknowns.
As I said IMHO. But he can freely ignore the comment :)
