Large drop in performance when going from version 4.6.0 to 4.7.2

[robokozo]

I just noticed that 4.7.2 was available but my small project using 4.6.0 is significantly slower when using 4.7.2 and Chrome Version 29.0.1547.76 m

4.6.0 http://jsfiddle.net/Robodude/myrfN/ http://www.youtube.com/watch?v=-hM2cTIJVgA

4.7.2 http://jsfiddle.net/Robodude/JE3m6/ http://www.youtube.com/watch?v=H4NuMXpxYgs

You might have to resize the jsfiddle 'Result' frame to get the canvas to draw.

Drag and canvas to scroll across the calendar. Notice the speed of the updates in each version.
