hi Chris,=20

i was looking at elmex's construder code recently, and noticed that the =
passing of an SDL surface to OpenGL was done by dumping the SDL surface =
to a BMP temp file (via File::Temp), then loading the BMP with OpenGL.=20=


obviously this solution is a little slower than others, but... it should =
'just work' without much effort

we could always use this lazy technique for initial testing, until a =
more 'correct' solution is sorted with SDL_Texture :)
