app_server: Basic scaling for window borders.

Browse Source 
This code is quite convoluted and very much in need of refactoring,
but this solution works well enough for the time being. It does not
look quite right at higher resolutions (borders come out darker than
they do at the default resolution), but at least the borders are now
the correct size instead of a constant one.

The resize nub drawing code also hasn't yet been updated, so while
it draws the gradient over the full resize area and responds to clicks,
the "checkerboard" pattern is drawn at a fixed small size still.

Nonetheless, this is a significant improvement.
