2001-08-02 Juergen Vigna <jug@sad.it>
* BufferView_pimpl.C (update): redone this function so that we
update the text again if there was a CHANGE_IN_DRAW.
* screen.C (cursorToggle): removed LyXText parameter and recoded.
(drawFromTo): added a new internal bool which is used by draw() and
redraw() function.
(general): some cursor drawing problems fixed.
