OpenGL on Windows

[Felix Bembrick]

Thanks Stephen.

If I were to build an OpenGL-based platform for Windows, would the font
rendering technique need to change?  That is, could DirectWrite still be
used to rasterise the glyphs (if that's what's currently happening) and
would there be any reason for the text rendering quality to degrade?

You mentioned that "ES2 code is not there": was that just an example or
will I really have to address this problem?

Thanks,

Felix
