In MyAES case, I send message for each rectangles to redraw of a

window is enough and finally more efficient, I will look at this.
Well, it only makes sense to merge areas which intersect, sending full
window
isn't a good optimization.... Of course it depends on the
application...
but with netsurf I keep a list of redraw areas, because it's faster to
redraw several small area instead of one large... but on the other hand
it's not fine to send WM_REDRAW for each small area... ( at least not
when
there is no optimization after the WM_REDRAW has been sent...) -
that's why
I manage an internal list of areas which require redraw.
If the AES would optimize the scheduled redraw areas, I would maybe
change
that behavior...
