Performance enhancements #109

Closed emxsys closed 6 years ago

emxsys commented 6 years ago

Patches the WorldWind 0.9.0 library with several performance enhancements, including:

Network request throttling to prevent flooding the browser request queue with requests during transits through the level sets.
Increased the size of WMS tile matix caches to prevent memory cache thrashing
Added the concept of volatile resources that are biased to be evicted from the GPU resource cache sooner than non-volatile resources
Fixed WMS level set configuration to use WMTS tile matix scheme to capitalize on server side caching

Closes #106 Closes #107 Closes #108
