Minor lifting in the render side, getting ready to just hunker down and take notes on whats next
* VEFontCache needs to get fixed up (possibly bring back ELFHash) * Problably going to do conversion early to odin's array and map usage * Need get the quad tree setup for the ui so that I can do fast and efficient traversal for the layer based rendering.
