Override Rect#contains() to include bottom right

In landscape, the lowest coordinate touch registered
is the actual lowest pixel possible by the screen.
For portrait/seascape the lowest coordinate
is (lowest pixel possible - 1). The difference of the
one pixel makes Rect#contains() return false since
only top left Rect points are inclusive and bottom
right points are exclusive.

Test: Always able to smoothly go to overview from
landscape.
