The OpenGL library.
◆ temp_context
| struct client_gl_context client_gl_win32_compositor::temp_context |
Temporary storage for "current" OpenGL context while app_context is made current using context_begin/context_end.
We only need one because app_context can only be made current in one thread at a time too.
