Fix fullbright alpha in fixed-function.
Prevent debug visualizations from writing to the z-buffer (caused occlusion weirdness)
Be super sure not to let rigged vert weights extend beyond actual joint count.
Lazy workaround avoiding undefined behavior for rigged meshes with invalid joints.

Let shaders dictate vertex buffer attributes for alpha faces (if shaders are enabled)
Experimental volume face batching changes (Cursory testing shows: +~10% larger mean batch size).
-Drive pass selection by face pools. Doing such removes a fair bit of redundant (and often buggy) code.
-Ignore irrelivant batch breakers depending on pass/pool type.
-Face sorting algorithm modified to potentially allow larger batches.
-Removed a few unused/broken things (bake_sunlight/no_materials)
-Fullbright handling should hopefully be a little more consistent.
-Prevent fullbright faces from being placed in 'simple' pool. (They are already simple-er)

Fixed attribute error that popped up with bump faces when batching was disabled.
Added missing can_batch_texture check. Fixes unbatchable faces occasionally getting batched with the last batchable face batch. This was mostly noticeable with animated faces.

Fix poor batching with mac/ancient drivers. Also, some minor tweaks to sorting algorithm.

Update qtoolalign (Fixes issue 704)

- Removes shortcut ctrl-a for align tool
-- to avoid ctrl-a for select all text in UI controls messing up prim selection
- Adds llselectmgr select all function
-- to replace ctrl-a select all prims functionality that was a side effect of qtoolalign having this shortcut
- Adds toggle button (up/down arrow) to build floater for toggling display of the lower tab container area
-- This is to satisfy users who relied on ctrl-a to use align while the build floater was minimized and out of the way
- Syncs qtoolalign from Alchemy
