44 ** This file defines the interface between the GL core and the surrounding
45 ** "operating system" that supports it (currently the GLX or WGL extensions).
47 ** Members (data and function pointers) are documented as imported or
48 ** exported according to how they are used by the core rendering functions.
49 ** Imported members are initialized by the "operating system" and used by
50 ** the core functions. Exported members are initialized by the core functions
51 ** and used by the "operating system".
55 * Mode and limit information for a context. This information is
56 * kept around in the context so that values can be used during
57 * command execution, and for returning information about the
58 * context to the application.
60 * Instances of this structure are shared by the driver and the loader. To
61 * maintain binary compatability, new fields \b must be added only to the
62 * end of the structure.
