LLWearableType::initSingleton() calls LLWearableDictionary::initParamSingleton().
LLWearableDictionary's constructor constructs specific WearableEntry
instances, each of which wants to translate its name string to a user-facing
label using LLWearableType::mTrans.

WearableEntry's constructor was calling LLWearableType::getInstance(). Under
circumstances we don't fully understand (recursive mutex misbehavior?), that
could hang.

Instead, pass the canonical LLWearableType instance to LLWearableDictionary's
constructor, and from there into WearableEntry's constructor.

Provide method of storing joint indices sep from weight data for faster runtime processing.

Revert attempted fix for 10625.

Fix OSX compiler error from missing defaulted param and changed signature of renderAlphaMaskTextures.

Add work-around for broken intel drivers which can't use glReadPixels from RGBA FBOs to get alpha without locking up.

Make shadowAlphaMask shader ignore vertex alpha before discards iff we're a fullbright object.

Keep llappearance from stuffing dangling pointers into the alpha cache (crash iff you're using nSight debugging and disable readbacks).

Fix glow calcs in sky shaders (not just the not shared enough atmospherics funcs).

Revert 10625 attempted fix as it breaks baggy clothes as much as skipping readbacks does.

Keep texture baking from pointlessly mercy flushing GL like a kid that just discovered the toilet handle.

Make glReadPixels call use GL_ALPHA8 (a texture format) instead of GL_ALPHA (an enum to indicate the alpha channel).

Appease Clang.

Move dynamic texture update (which does local back readback work) to just before swap
which may keep the Intel driver from tripping on its own shoelaces and is also subjectively faster for bakes.

Fix emissives without normal maps clobbering the alpha output in materialF.

Modify glow size calc to get close to pre-EEP sun glow behavior (may require sky vert settings >= mid).

Make bake ignore alpha readback for Intel until we can determine why their drivers now go boom.

Try aligning data used for glReadPixels to see if we can coax the Intel driver stack into being a less souciant pile of detritus.

Replace face color based test replaced with other logic in error.

[MAINT-8846] - fixing duplicate id in avatar_lad.xml fixrs character test female crash. code cleanup.

Modify autobuild.xml to use new libatmo w/ state save/restore fixes (addresses font render glitch).

Put in nSight debug support.

[MAINT-8081] - bakes on mesh. 1st pass. changed texture panel to select bakes on objects. handle magic bake ids in LLViewerObject.

libatmosphere integrated in indra/llrender/llatmosphere.cpp

Still working on runtime shaders to use libatmosphere precomputed atmospherics textures

These changes are only enabled if RenderNsightDebugSupport is true and eliminate use of
some OpenGL legacy functionality which is incompatible with nSight capture
(mostly glReadPixels and other fixed-function pipe rendering calls).

MAINT-7528 - allow underscores to substitute for spaces in uploaded meshes - this allows rigging to some attachment points that will not otherwise work

SL-704 - made avatar hierarchy more consistent by adding lluiavatar for viewer-local avs used in upload previews
