Fix graphics tearing and stuttering for disk images that sync to video scanner
...
- Use a second framebuffer to avoid tearing
- Occasionally stall graphics thread for ~4ms until CPU thread (video scanner) completes drawing a frame
- These fixes seem to essentially fix graphics issues with Dagen Brock's Flappie Bird (flapple140.po.gz disk image)
