Practically all fauna have a 2:1 length to width footprint ratio. However, citizen cavalry has a 3:2 ratio and worker elephants a circular footprint. This patch changes their footprints to the more appropiate 2:1 ratio.
This is how their footprints look as a consequence:
{F1182878}
A larger footprint also makes units more vulnerable to long range projectiles (e.g. arrows), so this patch makes citizen cavalry a smaller target. For comparison:
* citizen infantry footprint: 7
* cavalry footprint: 24→18
* champion and hero cavalry footprint: 19.6 (circular because of selection marker)
* worker elephant footprint: 50→32
* elephant archer footprint: 38→32
Also tweaked footprint height to:
* infantry: 4.5
* cavalry: 6
* kush and ptol camel: 7.5
* maur elephant archer: 9
* maur worker elephant: 8
