60 | * Include generated cdecl wrappers for stdcall WGL functions | |
61 | * | |
62 | * There are extensions to the wgl*() API as well; again we call | |
63 | * these functions by using wglGetProcAddress() to get a pointer | |
64 | * to the function, and wrapping it for cdecl/stdcall conversion | |
65 | * | |
66 | * We arrange to resolve the functions up front, as they need a | |
67 | * context to work, as we like to use them to be able to select | |
68 | * a context. Again, this assumption fails badly on multimontor | |
69 | * systems... | |
