Fix issue #5445966: WindowManager reporting -long on prime when it shouldn't be.

The window manager now uses the app screen dimensions to compute
the various configuration properties, as it should.

This means that prime is official a "not long" device.  Poor prime.
It probably feels inadequate now.

Because it is.

Oh and all that other stuff?  Debugging logs.  Turned off.  And
why the heck not, debugging logs are great.
