PEG w2sx--tjl: Replace w, h in most places by sx and sy

Author: Tuomas Lukka
Revision: 1.4
Status: Implemented

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.
