Please document the method including units for the height.  I believe that the
height will be in logical (device independent) pixels rather that physical
pixels.  Makes a difference on high-dpi devices.

I've refactored the changes and removed the keyboard resizer. And I've added
comments as appropriate in the new patch set.
