Blender Git Loki

Removed unused variable.

Some tweaking to UI, try to make filebrowser header a bit more compact...

Merge branch 'asset-experiments' into asset-engine

Merge branch 'master' into asset-experiments

Better handling of tags in Amber.

Also adds some 'state' flags to AssetEngine, so that custom AE's setting changes
can be notified to filebrowser, as default internal ones are.

For now, we only have 'dirty filtering' and 'dirty sorting'.

dynamic fracture: fix for loss of rotation, and transferring speeds of parent shards to children now

dynamic fracture: finally the transforms seem correct... but this mode still is highly unstable, and is prone to crash often, use sparsely !

Properly loop sound when reaching the end of a movie

Speed of sound would get reset when stopping and resuming.

Blenderplayer audio:

Start and pause support

Tackle some of the review points.

Blenderplayer sound:

Support speed of sound based on how fps is different from the movie fps.
For high fps the picture thread can lag behind the sound still, need
some way to framedrop.

Keep interpolation type of keyframes when cleaning

Not sure how well that will work in practice, but there's a
whole studio of people ready to test.

Squeakycleanlinator tool for Hwoozeberry.

Basically it's a clean tool, but also removes a channel if the only
remaining keyframe has the default value only and is not used by
drivers or generative modifiers.

It's supposed to help with performance of the heavy scenes in
gooseberry.

Field test in gooseberry for now, masterification later.

Use dedicated versions of shapekey eval functions for strands.

Strand shapekeys will be interpreted as delta keys without a basis,
since the basis would be animated and therefore useless for static keys.
To avoid complexity in the already overburdened shapekey functions and
to skip old legacy code, the strands shapekeys now have their own
functions.

Removed some useless old code.

Removed the complicated optional refdata handling from the generic
shape key eval function.

This now goes to a dedicated strands function which can be cleaned up
properly, all the old code can function as before.

Merge branch 'master' into gooseberry

Fixed shape key reference data usage, for applying shape keys on top
of an animated base.

This is necessary for strand shape keys. The basis of the data comes
from the cached animation or simulation results, i.e. we can't use the
fixed basis key or the result would always become static.

Some minor cleanup in Amber code.
