[SDL] glSDL backend

[Roberto Prieto]

So... what is the right way to use glSDL?

Could you explain to us or give an example?

I used glSDL as wrapper (v0.71) and it worked for me perfectly :), but now, 
I don't know if there are new improves and changes since v0.71 or not.

Anyway...glSDL is a fantastic project, congratulations to do it! and thanks 
in advance

Happy Christmas!!
