-----------
Fix for redraw issues when making fast strokes with grab tool in sculpt mode
Join redraw rectangles from previous step and current during one stroke
and reset previous rectangle when stroke is finished. This shouldn't cause
problems
with viewport changes during the sculpt session and this should emulate
object boundbox merging for states "before step" and "after step".
At leastm it's more logical because boundbox could not only grow up during
stroke, but it could also shrink down.
