manually revert change to canvas expose handling in fee026c5ef
...
Breaking out the rectangles implies a z-axis ordering of drawing,because the rect drawn last will implicitly be "on top".
But redraw areas are not submitted with any z-axis information, and so drawing like this breaks canvas layering. It
would be more efficient to draw the rects separately, but we don't have any ordering information and so we cannot do it
correctly.

a better, more general fix for the previous Canvas::item_going_away() issue. There is no need to repick the current item if the item going away is NOT the current item

When removing an item which is event-insensitive, there is no need to repick the current item, since it can never have been used as the current item.

This fixes crashes associated with ghost notes in midi regions.

fix redrawing of canvas with an optimized build
...
Best guess right now is that optimization does something bad when ceil() is called twice on a very large dbl-precision number,
which results in a zero (empty) redraw area. Without the removal of the redundant ceil & floor functions, no expose events
would be delivered to the canvas in an optimized build during drags (and maybe more).
