WebView 3.25: refactoring again and not the last:
- use X coordinate from draw, not column - make "zoom" var local, mostly use font_w instead - rework logic of reparsing document when the size of window changed - new: improve image positioning git-svn-id: svn://kolibrios.org@8457 a494cfbc-eb01-0410-851d-a64ba20cac60
