RE: [paragui-users] a few changes to PG_FileSelector

[Dinand Vanvelzen]

I've been discussing a way to merge OpenGL and SDL blitting functions.
You would normally use your SDL function but OpenGL would be doing the
blitting. This would also allow SDL code ( ParaGUI ;) ) to use hardware
acceleration.

Below is a quick grab from the SDL discussion.
Be sure to check out this link : http://olofson.net/mixed.html
By integrating or supporting it I think you can,.. with little extra
effort.
Get ParaGUI running in OpenGL WITH hardware acceleration.

Dinand Vanvelzen

Seems you are new to the list, please check out glSDL by David Olofson
at http://olofson.net/mixed.html. It does everything you said.
