GlobeControls: Understand why controls seem less responsive / slower depending on framerate #656

Even though pointer events are being used.

This may be specifically when the framerate is lower due to low battery meaning even events are fired less frequently and therefore (should) have larger values since more motion has happened between events. I've noticed this only with zoom and it's likely due to this zoom speed normalization function:

https://github.com/NASA-AMMOS/3DTilesRendererJS/blob/b3206619ea2a9b20f8aa40c6db8842e69ef89349/src/three/controls/EnvironmentControls.js#L432

which attempts to normalize zoom speeds by using a logarithmic scale. That means that larger movements will be scaled down causing a difference in apparent speed.

Not exactly sure what to do here.
