EGA palette range correction
|Reported by:||SF/lord_nightmare||Owned by:||Kirben|
This fixes the EGA palette so that the low two bits are not always 0 for each Red, Green, and Blue element. The reason that the current values are that way is because someone transscribed the standard IBM VGA-equivalents-of-EGA-pallete (which is 6-bits-per-color-channel) and didn't adjust the range when converting them to 8-bit values. [they only did (val << 2) instead of ((val << 2) | (val >> 4))] So, instead of 0x2A, 0x15, and 0x3F ending up as 0xAA, 0x55, 0xFF, they ended up as 0xA8, 0x54, and 0xFC. This patch fixes that. I can't think of any regressions this could possibly cause.
