iM1A2 Abrams and SetDIBitsToDevice

[gho]

At last I defeated also this one: "iM1A2 Abrams" renders to video using the SetDIBitsToDevice call on a 8BPP palettized DC, and since this is not supported on modern OS, DxWnd needs an emulation process.
Finally I fixed the previous one that was giving bogus colors. I don't know how many other games may take advantage from this fix (I fear not so many ...) but this game alone deserves all efforts, though it is rather old (1997) and with no fancy graphic, it is a pretty accurate tank emulator.
Her in attach all you need to run it. Just remember that the game is "delicate" at startup, it may easily crash before the main game menu, but fortunately after that it is pretty as robust as a tank!
