libstage: remove everything dimensional

Having the stage manage the rendering dimensions for nodes
seemed like a good idea at the time.

This commit removes all that so there's no more coupling to
SDL or dimensional types.  Now the stage really is nothing
more than a thin drawing list abstraction.  The layers can be
used for ordering the drawing, which is the only semi-dimensional
thing remaining.

The stage_fit() helper remains for now out of convenience, but
it's really out of place in this library.
