Starting on line 3905 of jquery-1.3.2.js we have this code:

// We need to compute starting value
if ( unit != "px" ) {
    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.
