There are two ways to approach this, the easy way and the hard way.  =20
The easy way would be to find a way to make the compiler stop =20
complaining.  Actually, I am surprised that it is an error rather =20
than a warning.  What happens if you use reinterpret_cast instead of =20
a C-style cast?

The harder way would be for us to stop using a pointer as an OpenGL =20
texture name.  Instead perhaps we could use glGenTextures, and add =20
that field to the TQ3CachedTexture structure.=
