st/texture-cache: Set up sliced images to fill parent

Browse Source 
When using fractional scaling, the size of the loaded image with
applied scaling may still differ from the displayed size. This
is currently addressed by syncing the size of all slice actors
in the (probably only) caller.

Instead, set the actors to fill their parent automatically.
