Well, the attached patch does exactly the same, it's just a little more
verbose about it :-)
Anyway, we do not support OVERLAYS and UNDERLAYS in OpenGL right now (I do
not even know how we could do *that* with GLX) so your code should be about
right.
Moreover, according to MSDN, War3 should never call wglSwapLayerBuffers as
we do not have the 'PFD_SWAP_LAYER_BUFFERS' bit set in our
PIXELFORMATDESCRIPTOR (oh well, that is Windows programs for ya :-) ).
Could you, out of curiosity, add me a log showing what value War3 uses in
the fuPlanes field ?
Changelog:
Jesse Allen <uh_ja@gmx.net>
Lionel Ulmer <lionel.ulmer@free.fr>
- add implementation of wglSwapLayerBuffers
Lionel
PS: War3 running in Wine using OpenGL !!! Man, this is nice :-)
