[fpc-devel] Fixes to OpenGL bindings

[Michalis Kamburelis]

Hi

I'm attaching a trivial patch for OpenGL bindings that

1. Fixes declarations of glGetMapiv, glGetMaterialiv and glLightiv to 
take pointer as the last parameter.

2. Changes glGetString, gluErrorString and gluGetString to return PChar 
instead of PGLubyte. After all, GLubyte and Char are the same thing 
internally but for Pascal declaration PChar is more comfortable than 
PGLubyte, since these functions always return null-terminated strings. 
This is even proved in GLext unit implementation where you have to 
explicitly cast result of glGetString(GL_EXTENSIONS) to PChar all the 
time :)

I also submitted these changes to Tom Nuydens and to jedi-sdl (for 
Delphi/Kylix users that use version of these units from jedi-sdl), so 
all three copies of these units stay synched.
