FWIW, it works fine here on SDL 1.2. SDL 1.3 is a different story 
altogether, having new internal interfaces which mandates a rewrite of 
glSDL.

As a side note, they complained about lack of accelerated lines once. 
Drawing software lines and uploading them to OpenGL is really too slow. 
I think that's the reason that pushed that project to integrate a 
variant of glSDL and change it to suit their needs.

The internal SDL API has changed. I don't really have time to invest 
into learning it right now and porting glSDL, I'm already quite busy 
with other projects and work. So I guess it's up to you David :D

Same here. Sadly.
