* Macros for handling GL dispatch tables.
90
* For each known GL function, there are 3 macros in this file. The first
91
* macro is named CALL_FuncName and is used to call that GL function using
92
* the specified dispatch table. The other 2 macros, called GET_FuncName
93
* can SET_FuncName, are used to get and set the dispatch pointer for the
94
* named function in the specified dispatch table.
