	Starting on line 3905 of jquery-1.3.2.js we have this code:
    
	// We need to compute starting value

	self.style[ name ] = (end || 1) + unit;
	start = ((end || 1) / e.cur(true)) * start;
	self.style[ name ] = start + unit;
	}
    
	This creates a problem where we cannot give units to our custom animation
	because if we do then this code will execute and because self.style[name]
	does not exist where name is our custom animation's name then e.cur(true)
	will likely return zero and create a divide by zero bug which will set
	start to NaN.
    
	The following monkey patch for animate() gets around this by storing the
	units used in the rotation definition and then stripping the units off.
