Slider should not force a redraw
Slider should not force a redraw

A redraw() resets the tiles, which means they have to be fetched and
decoded again.
Not sure if this will work since it uses an internal function, and might
do the wrong thing when the affected layer is not the top one.  But so
would layer.redraw().
