Draw manipulator from widget callback (handling still done separately)

Merge branch 'master' into wiggly-widgets

Fix for scons files missing physics include folder.

Yet another attempt to solve OSX issues, restore sequence sounds too, or
sounds get added to two sequence and file descriptors leak

Added separate damping for bending springs.

The bend damping factor was hardcoded to the same value as the stiffness.
Now it has its own factor in the settings and button in hair dynamics.

Minor corrections to the types

New data types for sequencer.

Uses struct hierarchies to reduce the data used per strip.

Also changed sequence -> strip. Might be better to use NSequence for
editing as well.

Merge branch 'master' into terrible_consequencer

Set the length threshold for hair simulation to 10% again (from 1%).

With the default 5 substeps the simulation can otherwise still become
unstable. This is just a preliminary measure anyway until the length
variance can be fixed properly.

Fix for outdated root array size when changing the particle amount
during simulation.

Fix for hair chain testing in the cloth modifier.

Bending springs are en-bloc and not interleaved with other springs, so
this can't be used as a test for hair roots. Use consecutive indices
instead.

Completed the implementation of bent rest shapes for hair.

Basically follows the Pixar approach from "Artistic Simulation of Curly
Hair".

Gooseberry request: Backdrop for sequencer.

Add missing notification for trimming to stop showing the extensions

Gooseberry request, hide the extensions except when trimming.

Get rid of temporary flags when loading the sound.

Attempt to fix OSX issues (again): cleanup the loading flag for files
that are loading when interrupted.

Target calculation for local non-straight rest shapes.

This is more involved than using simple straight bending targets
constructed from the neighboring segments, but necessary for restoring
groomed rest shapes.

The targets are defined by parallel-transporting a coordinate frame
along the hair, which smoothly rotates to avoid sudden twisting (Frenet
frame problem). The rest positions of hair vertices defines the target
vectors relative to the frame. In the deformed motion state the frame
is then recalculated and the targets constructed in world/root space.

Have to include BLI_utildefines before BKE_collision now to have bool
defined.

change widget code, area now just stores a pointer to the widget list
corresponidng to it.
