Physics for the lazy demo slow in Firefox. #29

Apologies if this is the wrong place - it's the closest I could find to a project related to your post "Physics for the lazy".

The line: ctx.globalCompositeOperation='overlay'; ...makes the demo insanely slow in FF.

The Firebug profiler shows that, with this line, the line: ctx.stroke(); ...uses about 99.99% of the cpu time.

The demo runs at a normal speed without the 'overlay' setting.

System: FF29.0.1, Win 7, Nvidia GeForce GT 650M
