Brian Tarricone c4ae1a55fa fix case when EGL driver doesn't support EGL_NATIVE_VISUAL_ID
Some EGL drivers, such as the PowerVR simulator (and some proprietary drivers)
return zero when the EGLConfig is queried for the EGL_NATIVE_VISUAL_ID
attribute via eglGetConfigAttrib().

This patch detects and attempts to work around that situation by picking a
visual with the same color depth.
