Add some more specification to the attribList used for setting up our wxGLCanvas. It turns out that wxMSW will set PIXELFORMATDESCRIPTOR.cColorBits to 0 if there isn't anything in the attribList to specify a desired number of bits, which may be what some OpenGL drivers break on. (Shotgun debugging at its finest.) 

Originally committed to SVN as r5739.
