Subject: [SDL] [PATCH] SDL bug patch
Let me introduce 2 fixes to SDL.
1. Preventing great slowdown on fast machines while hardware
flipping (it's obviously bug).
2. Setting up 85 Hz of monitor if supported. The reason is that
Win98 by default sets lowest frequency 60 Hz.
And we can't set up maximum frequency because some users can have
wrong monitor drivers.
This is important for shareware and commercial programs.
