9Some remarks:
10* The new OpenGL units are not 100% compatible to the old ones; the new units
11 use exactly the same function declarations as their C counterpart.
12* Platform compatiblity: You can work on all targets exactly as on Win32;
13 for example, you can use wglGetProcAddress for loading OpenGL extensions even
14 on Unix based systems. A future release of the glext unit might have helper
15 functions for loading specific extensions. (There is a small problem with
16 Free Pascal: In FPC mode, you cannot assign a pointer, as returned by
17 wglGetProcAddress, to a variable which holds a function pointer. Currently
18 you have to compile your programs in Delphi mode, if they are using OpenGL
19 extensions)
20* GLUT on Win32: Get the glut32.dll from here:

22* GTKGLArea: The GL Area widget for GTK is available in the GTK package
