nigthmare but I learnt a few things about canKS
FAILS silently!!!very ad. If css is wrong, nothing happens, no error is printed.
Important!! the vew has be initialized with an observable to react to changes...
Events are not triggered... nor with can.trigger or $.event...
So width is wonrg and height too when it reaches the border of the page.
finally corrected many things so that it now works with mouse move and mouse stop!!!
Lots of refactoring to do though
Also I am now using fragments...
