To WILL: That is really way back because on my site there is a version which can use OpenGL just as plain SDL since 2005. Pay attention to TSDLGL... classes on http://sdlcontrols.sourceforge.net/sdldraw.htm

To cairnswm: Before I sent my mail I was looking around this please and I found and downloaded your libraries. I had a quick look over them and it seams to me that we have some similarities in our work. Anyway, for my controls to be able to work on all libraries they will need just what you are making only I wasn't aiming for simplicity but complete usability.
