 Ready-made bytes for plotting two-pixel points in the dashboard (the bottom
 part of the screen).

 There is one extra row to support the use of CTWOS+1,X indexing in the CPIX2
 routine. The extra row is a repeat of the first row, and saves us from having
 to work out whether CTWOS+1+X needs to be wrapped around when drawing a
 two-pixel dash that crosses from one character block into another. See CPIX2
 for more details.
