|
* different threads, so for these calls, we are actually linking to the system's/ICD
|
|
* opengl32.dll directly, so that we are guaranteed that the "right" versions of these
|
|
* WGL calls are carried out. This must be a separate source file because we can't include
|
|
* the system's GL/gl.h with epoxy/(w)gl.h together in a single source file. We should not
|
|
* need to use these when we are creating/initializing a WGL context in GDK, since we should
|
|
* be in the same thread at this point.
