Correctly specify the visible part of the rightmost tile when the current
resolution is not a multiple of the tile size, in emulation (text) mode.
The usual 1280x1024 resolution ended up with the correct value, by chance,
but a width of 1600 would be wrong. (X11 was running fine)
Tested on the 1600x1024 resolution of the 1600SW display. Thanks to Johan
Sanchez for lending me a 1600SW monitor and an adapter board.
