The image shows how the default colours can be overridden with routines
PGSCRN (or PGSCR). On devices with a colour lookup table, changing the
background colour takes effect immediately, but on others it only affects
elements that are explicitly drawn in the background colour.
Thus it is necessary to fill
the page with the background colour, which is here done with PGERAS,
before drawing anything else (this means that PGENV cannot be used)
