Well,
I am implementing OpenGL 1.2 and 1.3 features in the code, now, there is no need for all those texture conversions that were done, OpenGL supports all Glide texture modes, so the format is a direct one, I test it and it is very good, compile the new version and give it a try. Take a look at the PGTexture::MakeReady function to understand what I did... 😀
