* Functions are provided for:\r
*\r
- * - initializing one of the available modes\r
- * - setting the start address of the VGA refresh data\r
- * - setting active and visible display pages\r
- * - writing and reading a single pixel to/from video memory\r

Perhaps a little diagram will clarify it. The following picture is of a\r
standard X-mode addressing scheme with the OFFSET register set to 80.\r
\r
- ROW OFFSET\r
- 0 0 ========================\r
- 1 80 [ ]\r
- 2 160 [ ]\r
- .. .. [ VISIBLE ]\r
- [ SCREEN ]\r
- [ ]\r
- [ ]\r
- .. .. [ ]\r
- 199 15920 ========================\r

\r
and the next diagram is of a modified addressing scheme with the OFFSET\r
register set to 82 (to give us 4 extra pixels on each side of the screen)\r
