IIe double modes

[Jonathan Schattke <wizwom@ripco.com>]

I got a second-run //e to help me verify AppleWin's functionality, and
one of the first things I did was to check out the Double-Hires &
double-LoRes graphics.

The following anomalies occurred:

If I turn on AN3 with poke-16290,0 and have the machine in 40-column
mode, Lo-Res mode is 40x40, but the colors are as if the screen was
directly mapped to hi-res.

If I then turn on 80-column mode, the lores is 80x40, but the colors for
the aux bank pixels are mixed up, 0,8,1,9,2,10,3,11,4,12,5,13,6,14,7,15
corresponding to 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,and 15.

Also, I seem to get slightly different colors in DHR mode: 32 of them (I
guess this is because a DHR pixel is half a pixel).

Do these anomalies happen with a IIc or enhanced IIe?

I'd really like AppleWin to be 100% accurate.
