Subject: [PATCH 1/3] Properly set and unset `_replotting` flag during scroll
 event

This is set to `false` in `zoomWheel`'s redrawTimer, but a corresponding
set to `true` was missing.

Subject: [PATCH 2/3] dragbox: Add early return when scrolling multiple
 subplots

This prevents multiple subplots from firing their `setTimeout` callback
which otherwise leads to erratic jumps in the plots when
scrolling/zooming with the mouse while moving it at the same time.
