Yuan says it's pEntry, I came to the conclusion it's probably a counter,
because it's values are small like 1,2,3..0x200
see http://www.reactos.org/wiki/index.php/Techwiki/win32k/GDIOBJHDR
Has probably changed from 2k to xp.
I agree, DX objects might be different, maybe they have a different
header structure, I have never looked at DX object memory, so I don't
know how they look...
I just can say that all GDI objects I have dumped the memory of, don't
have a type field there, it's always been 0.
