Fix multi-line selection with single cell end

When the user selected multiple lines, dragging the selection downwards,
and then leaves the cursor to the left side of the first cell, the first
cell was still incorrectly selected. This has been fixed.

The selection also did not update if the mouse was outside of the
window, now all movement events are accpeted even when the mouse is
outside of the window. This allows updating the selection when the user
is dragging the cursor too far.

Mouse movement and click events outside of the window are not
propagated, these are only used for updating the selection.
