I have been looking at fl_BlockLayout::checkSpelling() and friends,
and it seems that every time this function is called by the timer and
the squiggles change, we do a screen update. We should really only
do screen update if the current block is on screen. Is there any
simple way of checking whether a block is on screen or not, or do I
need to design a function for that?
Also the flipping of cursor on and off from within this function results
in frantic flicker of the cursor when a document was just loaded and
all the blocks are being processed.
