|
* This is a private copy of mcdrv.h with all the 1.0 stuff
|
||
|
|
* stripped out. It allows OpenGL to build for MCD 2.0 even though the
|
||
|
|
* public header file doesn't include the necessary information.
|
||
|
|
* Some things changed from 1.0 on and these cannot be redefined in
|
||
|
|
* a safe manner so they are not present here, causing some weirdness in
|
||
|
|
* the code but much less than ifdefing everything.
