Have you checked the font is rendered correctly?
Yeah, it works fine.
The font should be
transparent and the blend function reads the alpha channel to
determine the transparency, so A8 would be a better option. If that
isn't an option either, the fragment shader should do .xxxx swizzling.
Hmmm, I just tried A8 and it text is missing.
I figured you were using a KIL-based fragment shader for the text as
in the state tracker's glBitmap code.
I'll look closer later...
