public Object evaluate (float fraction, 
                Object startValue, 
                Object endValue)
    
    
    
  This function returns the calculated in-between value for a color
 given integers that represent the start and end values in the four
 bytes of the 32-bit int. Each channel is separately linearly interpolated
 and the resulting calculated values are recombined into the return value.
    
    | Parameters | 
|---|
      
        | fraction | float: The fraction from the starting to the ending values | 
      
        | startValue | Object: A 32-bit int value representing colors in the
 separate bytes of the parameter | 
      
        | endValue | Object: A 32-bit int value representing colors in the
 separate bytes of the parameter | 
    
    
      | Returns | 
|---|
      
        | Object | A value that is calculated to be the linearly interpolated
 result, derived by separating the start and end values into separate
 color channels and interpolating each one separately, recombining the
 resulting values in the same way. |
