OpenGL text rendering with Qt raster painter onto texture

Hi there,

rendering Text in OpenGL isn't as simple when i18n is required. Since QPainter and the font/text drawing features work pretty well, I was wondering if anyone has ever tried to do something like:

- use QPainter and draw text to render on an QImage
- use image as texture in QOpenGLTexture
- render Text as transparent texture to 3D plane in OpenGL

The advantage of this approach is, that all the special handling of font kerning etc. is already done by QPainter and Co.

The procedure appears to be pretty straight forward, but if anyone has a working solution (ready-made function) for that, I'd appreciate the input (and savings in own development time :-)
