New build...

Major changes since the last build is that plenty of code got rewritten. Many off-by-one-scanline graphical errors were corrected. Since so much code was rewritten, may possibly be buggy.

* Adjusted timing code, Many off-by-one scanline errors were fixed. Notably in Zelda oracles, Super Mario Land, Dragon Warrior 3, etc.
* Rewrote scanline-buffer code. Properly supports split windows, fixes Oracle of Ages intro, Donkey Kong, etc. Faster too. Also fixed bugs where window was displayed one scanline too far down.
* Double Speed = Timers now doubles length of vblank period when the GBC uses double speed. Fixes glitches in Balloon Fight GB.
