* Include generated cdecl wrappers for stdcall WGL functions
|
|
*
|
|
* There are extensions to the wgl*() API as well; again we call
|
|
* these functions by using wglGetProcAddress() to get a pointer
|
|
* to the function, and wrapping it for cdecl/stdcall conversion
|
|
*
|
|
* We arrange to resolve the functions up front, as they need a

|

|
|
* a context. Again, this assumption fails badly on multimontor
|
|
