[Laszlo-dev] anyone know where these "LzSprite.prototype.CSSDimension: coerced NaN to 0" warnings come from?

[P T Withington]

This warning is created when you try to set a dimension of a view to  
NaN, so somewhere the test must be doing a computation that is going  
off the rails. We used to silently ignore this, but it broke some  
runtimes.  I guess the only way to debug this is to run the test by  
hand.  Maybe you have to change CSSDimension to print out a backtrace  
(and run the test with backtrace on)?
