~50px pointer barrier in gnome shell at bottom of primary monitor

[Britt Yazel]

[Impact]
There is a pointer barrier at the bottom right hand side of the primary monitor, that was designed to make it easier to hit the hot corner. However in 3.6 this hot corner no longer exists (tray is activated by dwell on bottom on screen) so having this barrier no
longer makes sense.

On a Multiple Monitor setup, this barrier blocks mouse movement through the bottom 50px on right hand edge of primary monitor.

[Test Case]
- Setup a second monitor to the right.
- Try to move mouse through the affected area, it will block.

[Regression Potential]
Low, This is a backport of an upstream patch that landed very early in the 3.7 cycle. It just removes the barrier.

=== Original Report ===
There is a ~50px pointer barrier at the bottom of the primary screen in gnome shell where the messaging tray is, though it is persistant whether or not the tray is showing. This makes it so a cursor cannot pan from one screen to another with dual monitors in the lower region of the screen.

This should have been removed, since the hot-corner no longer exists in 3.6. However looks like the upstream patch only landed in 3.7. I will backport this when I get a chance.
