zoom-canvas 1.0.1  9-jun-2013
- Bugfixing - (mitigated) "zoomfit" bug
- "zoomfit" method was inherently imprecise due to underlying bbox command whose "return value may overestimate the actual bounding box by a few pixel".
- Now "zoomfit" method is simply "less" imprecise
- Now "zoomfit" takes care of canvas border and highlightthickness, too.
