42 * glutCopyColormap() --
43 * glutSetKeyRepeat() -- this is evil and should be removed from API

49 * This functions checks if an OpenGL extension is supported or not
51 int FGAPIENTRY glutExtensionSupported( const char* extension )

58 * Make sure there is a current window, and thus -- a current context available

64 * Not it is safe to query the extenstions
66 extensions = glGetString(GL_EXTENSIONS);
68 freeglut_return_val_if_fail( extensions != NULL, 0 );
71 * Check if the extension itself looks valid
73 for( i=0; i<strlen( extension ); i++ )
74 if( extension[ i ] == ' ' )
78 * Look for our extension

139 * This is simple and not demanging...
