I take this to mean as a matter of meta-code:

SET a 're-draw wanted' semaphore whenever exiting the
GR_Caret code with a 'change in document' state

ALSO: SET a 're-draw wanted' semaphore every 1/10 second AND
abiword has focus (to keep the screen fresh and to let 'caret'
'pulseing' or flashing on and off to appear)

ALSO: SET a 're-draw wanted' semaphore whenever any process or
sub-process of abiword 'gets focus' (mostly to handle the
start up case, but also 'just because')

------------

then, in the 'document redraw' code, test the 're-draw wanted'
semaphore, and when it is set, ... redraw
