A few comments concerning the opengl stuff:
- When an empty string, such as "<rt><font=SansSherif></font></rt>" is to be rendered using an opengl surface, a segfault occured. The solution implemented here prevents any gl call if width or height is <=0. The surface will still be created and cached.
- The repetition occured because the blit function scaled the texture space coord but still draw the whole rect passed in. I corrected that by ensuring the clipping rect is no larger than the texture in the Graphics blitrect function.
- I did experience the white backgrounds behaviour at some point during testing, but it seems that with these two fixes the problem is gone.
