Missing WGL function declarations in wingdi.h

[Aric Cyr]

As the subject says, all of the WGL functions that should be declared in
wingdi.h are currently only found in dlls/opengl32/wgl.h.  I ran across this
recently while working on getting wined3d to use wgl instead of glx directly. 
Currently I work around it by including wgl.h and adding makefile include
options to point to dlls/opengl32.  It would be much cleaner and correct if I
could forgo this and just include wingdi.h.  Anyone have problems with me
submitting a patch which would move the relevant (i.e. not all) parts of
dlls/opengl32/wgl.h into include/wingdi.h?
