    Have you done something unthinkable like, say, reading the patent? It's available from the USPTO website, you know?

    Re: glXGetProcAddress

    a) Cherry pick whatever you need from the glext.h file found at the extension registry and put it in your own private file.

    b) Make a private copy of that file and ship it with your project.

    The whole extension mechanism is well documented. The spec files provide prototypes for new functions and new tokens. This file, glext.h, does not exist _anywhere_. There are OpenGL...

    Re: GL_ARB_fragment_program and glDrawPixels

    Actually it's very dependent on the driver version and on the format you use. Want to be sure which is faster? Benchmark at runtime.

    Re: printing text (in Linux)

    your program is leaking displays.

    Char 32 is space. You want 176, i.e. you want 145 elements. Does that help? You said you changed this, but you don't say which characters you can't print.
