LLWord should persist till the end due to wide usage.

Pausing clouds should not pause water

following promotion of DRTVWR-540

SL-17194 Impostor quality pass 2 (and fix for fully transparent rigged attachments rendering to depth buffer)

This reverts commit b45c0e3e.

Merged previewAvatar and generateImpostor into a single function since they are nearly identical

SL-17077 Ensure profiling is disabled if gpu_benchmark fails.  Log the source of the real crash for when the viewer inevitably crashes later.

SL-17028 Fix for inconsistent ordering of transparent rigged meshes and removal of glow-only rigged meshes from depth buffer.

Might be a better idea to turn LLWorld back into an LLSingleton. Too many things to track.

When animesh stops being an animesh it might still be in a list, but will no longer have an avatar

More DRTVWR-550 Teamcity build fix. another piece of python2 syntax leftover in an error handling block
