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.
