1. Optimization of the mode 320*200*256. Load on CPU is less. Small increase of speed.
2. Optimization of the mode 640*480*16. Substantial growth of speed. 3. At the expense of deleting the superfluous code from vga.inc the size of a kernel has decreased. git-svn-id: svn://kolibrios.org@117 a494cfbc-eb01-0410-851d-a64ba20cac60
