Many places in the API use w and h like ::

    abstract public int ortho(int into, float depth, float x, float y, float w, 
float h);

in VobCoorder. This is not right, in the light of the new box coordinate system.
Most instances of w and h should be renamed to sx and sy.

No semantic changes; just a name clarification.

Pretty trivial.
