I've been cleaning up some graphical routines I've written in allegro,
and one thing I've considered is using vsync() to do some drawing during
the "vertical retrace".  But I'm working on a notebook, which means an
LCD screen instead of a CRT.  Is there something analogous to a vertical
retrace with LCDs?  I'm familiar with CRTs, but LCD displays are still
new to me.

Thanks
Jeff
