frontend for emulators in opengl

[Nitrogen]

If you are using Font4.pas to render out the Font Studio fonts (that procedure above comes from / was derived from Font4.pas) then it will draw the bitmap font characters upside down by default because of this line:

const
      USE_INVERTED = true; //Use this if you use inverted GL coordinates
                                     //where (0,0) is the top left corner.

I see you've just fixed it manually, but setting that to false may have fixed it too.
