Performance Roadmap

[kring]

This issue is an inventory of issues and ideas for improving Cesium for Unreal's performance. While we think the performance is pretty good, improved performance has a major impact on the user experience, so it's worth investing in.

This is a work in progress, please add to it!

Improvements to the algorithm that decides which tiles to render and which tiles to load and unload, and in what order.
