EnhMeta (not 16 bit) look at my code example, it's a DC with the EnhMeta bits set in
the handle table, most of the work is done in gdi32. Wine again is a good example.
Meta (16 bit) is created in gdi32,,,,, but,,,,, the dc handle is created via
nt create object. It works out side the normal DC mode of thinking.
Still, just like wine does it,,,,,, it is all handled in gdi32 not win32k, looks
like a gdi32 script player.

Already done. Wine test with hooks can reveal the truth. Also there is nothing
wrong with that at all.

I have ideas to fix this. Blame GvG for this one!
