Fix Fractal Pixel animation (#26463)

Browse Source 
This change does two things:

* Rounds up instead of down, so that a low count check isn't needed.
* When the matrix col is odd, by rounding up, and checking if the right
and left indices are the same, skip one since we don't need to process
the same column twice.
