Non-uniform border-radii are already supported when using a gradient
background, this patch adds support for solid colors as well.
The currently applied technique of using corner textures and filling
the remaining area with rectangles is extended, so that each corner is
padded with rectangles to the size of the largest corner.
Add border-radius.js to test cases, to test non-uniform border-radii
with both solid color and gradient backgrounds.

Reorganize the existing code which parses the -st-shadow property
to allow parsing different shadow properties and add support for
the text-shadow property.

Add basic support for background-position, which only supports absolute
values.
Also don't require an unit to be specified for 0 (because the unit does not
really matter here 0 is 0 regardless of the unit).

The idea behind this move is that we have a lot more control over
rendering if StWidget isn't a big pile of actors, and things are
more efficient.
