- * Notes:
- * - Each thread gets its own WGL context.
- *
- * - The WGL contexts share texture objects.
- *
- * - When 't' is pressed to update the texture image, the window/thread which
- * has input focus is signalled to change the texture. The other threads
- * should see the updated texture the next time they call glBindTexture.
