Bitmap font support files

[jalih]

Hi all,

I have added initial support for AngelCode.com's Bitmap Font Generator output data files into my simple game framework. So now it's really easy to achieve hardware accelerated drawing for games using GL Galore.

All it takes is just three lines of code and output files from Bitmap Font Generator. There is no need to use my full game framework.

Fetch it here along with a demo.

I have added some useful functionality:

- Calculate size of the text rectangle
- Handle clipping
- Center text inside the rectangular area
