Remove useless/repetitive code

fixScale(float) method has been extracted from the code but the original
code has been kept in place. Because of this, the animation scale is 
"fixed" twice which is not necessary. This patch, simply call 
fixScale(float) once and stores the result of it in the scale variable.
