[Vm-dev] Cog VM idling performance

[Juan Vuletich (mail lists)]

Hi Phil,

Take a look at the two numeric classVars in WorldState  
class>>initialize. Change their values, see how they are used. You can  
control the performance dependence on the mouse events. This works ok  
on your image, at least on a Mac.
