If ```wglMakeCurrent()``` is called from outside of epoxy (in a way that might change the device or pixel format), then epoxy needs to be notified of the change using ```epoxy_handle_external_wglMakeCurrent()```. + +The win32 dispatch layer is currently slower than it should be in the +single-context (or multi-context, but same device and pixel format) +case. We need to switch to using the linux-like function pointer +stubs, and detect when transitioning to multi-device/format and hook +in the per-thread dispatch table at that point. + +The win32 wglMakeCurrent () variants are slower than they should be, +because they should be caching the resolved dispatch tables instead of +resetting an entire thread-local dispatch table every time. |
