I was thinking about, to do the mouse wheel zoom like follows:
the mouseActions would observe, when it was last times zoomed, and if
the time period would be smaller, than some interval, than d.rast/vect
would *not* be called, only the pixmap would be resized.
if the time period would be "big enough", than new pixmap would be
rendered
currently everytime you change zoom scale, new map is renderd, which
does need to be fast enough, if you are zooming over big scales.
what do you thing about it?
