#   # While this does technically pad something it does not take into account the size of the primitive/component.
#   # Top and left padding should work no problem but to pad from the bottom or right the size must be taken into account.

#   # Take number of pixels to pad by and coordinates to start padding. Returns {x, y} for padding
