The missing blend function was causing the default of GL_ONE,
GL_ZERO to take effect, making it look like alpha blending wasn't
working. It would start working once the 9-patch shadow was rendered
since that code sets the correct blend function. Fix this by
ensuring we set the blend function wherever we use blending.
This removes the hard-coded limit of 1024x2048 tile sizes, and allows for
arbitrary tile-sizes. It will still only allocate texture sizes in powers of
two, however. It replaces the tile size with a buffered-area size, which can be
re-allocated as the screen dimensions change.

Scrollbars now have rounded endcaps, are a little smaller, and there
is a 1-pixel gap between the bar and the edge of the viewport. Just
generally making them look nicer.
