In some cases, arithmetic results (in particular from division) on zoom
levels return floats; however, the PyQt API requires int values to
function correctly. Therefore, explicit conversion to int or integer
division has been added for these cases.
A behavior bug causing sudden crashes was fixed. When a rectangular box
is dragged with the right mouse button, but the left mouse button is
touched prior to release of the right mouse button, the program
crashed. The root cause seems to be that this deselects the dragged
object so it is no longer available (i.e. `self.canvas.selected_shape is
None`). The new behavior does nothing / cancels the operation if this
occurs.
Added a shortcut for switching file format (CTRL+Y) since I often use
this functionality.
Steps to reproduce this particular issue:
1. draw a box
2. select the box
3. hover over one of the corners as if you want to resize the box (no click needed)
4. press DEL to delete the box
5. left click on the canvas
Note there are two more destructive operations on the canvas' `shape` in
`undo_last_line` and `reset_all_lines`, but former is dead code and latter
I don't know how to trigger. Thus I can't be sure un-highlighting will not
lead to visual glitches.
There are other potential fixes, e.g. checking in `selected_vertex`. I can
rework the patch, but then again, the fix is so straight forward that telling
me is probably more effort than just rewriting it.

Update pcl_ros to use the data() member function of STL containers to
get the pointer to the underlying storage, instead of dereferencing the
zeroth element and taking its reference. When a container is of size 0,
dereferencing element 0 with operator[]() is undefined behavior, and
will trigger assertions when features like _GLIBCXX_ASSERTIONS are
enabled.
Fixes#333.
