PixelFormat issues under Win32

Greg,

In general, here's what I'm trying to do to get around various PixelFormat
issues:

1) I'm trying to add more than one pixel format option in wgl.c

At least one app we've run needs to see a GENERIC_FORMAT as a fallback option.
Also, it appears that some apps just NEED to fish through a list of available
PixelFormats, try them on, and then go with one of them.

2) That means I've got to add an extra hashtable into stub that tracks pixel
formats for HDCs.

Apparently apps don't like it if they set the pixel format to n, and then get
back a pixel format of 1!


I'm just testing some of this out as we speak, so I'll get back to you
tomorrow with more results.

Thanks,
Jon Marbach
