due to the different meanings of the fgColor and bgColor

fields of a grafport vs. a cgrafport. In a grafport, those

fields contain magic numbers, but in a cgrafport they
|
|
contain colortable indices. This means that if a grafport
|
|
is turned into a cgrafport, the old values may cause
|

trouble. This makes me wonder whether or not our use of
|
|
them as indices is really correct. W/o the following fix,
|
|
LogDig will erase magenta when you open a file and then
|

use Cmd-= to create a check-box, if you check and un-check

the check-box. */
