Merge remote-tracking branch 'origin/master' into experimental-build

First (awful) tests to get a whole blend file content shown flat

Main goal is to see whether we can use existing filelist to handle that
(by default it is 100% tree-oriented).

Also, getting some strange issues with ID name currently...

Primitive hair lighting in OpenGL solid shading, cleanup of strands
drawing code for edit mode.

The lighting uses the same method as the particle hair, interpreting
strand direction as the normal. This is nowhere near realistic hair
shading, but doing this with line shading alone in the fixed-function
pipeline is probably not possible. A GLSL shader could be used instead
for a more realistic alternative as part of the viewport project. At
least this simple shading mode gives some orientation feedback while
editing hair.

Depsgraph: Add scene.depsgraph_rebuild()

This could be handy for the time being all the areas does proper
tag for relations rebuild.

Depsgraph: Remove simulation API

It was only needed for the time being no callbacks were filled up,
and this API was only running dummy operations which i basically
sleep for random number of milliseconds.

Now we've got real callbacks and don't need simulation any more.

A counter-kludge to work around linking problems our __finite() wrapper not being found

More mingw64 & c++11 - Python vs Math (::hypot) issue

More mingw64 & c++11 fixes - Compiler didn't like isnan() -> _isnan()

More mingw64 & c++11 math fixes

M_PI was undefined for some reason - probably one of the headers undefines it
or something. Nevertheless, this is the quickest fix to get this working

Silence compiler warning about unclosed comments

More compile fixes for mingw64

Swapping order of Python and cmath includes again for audaspace

Sequencer: fix for random crashes (after duplicating or cutting strips)

Display basic brush properties in the toolbar for hair edit mode.

Use the "official" brush size calculated by blenkernel and subdivide
the stroke step to avoid tunneling.

Filter affected hair vertices in edit mode based on the brush size and
z depth.

Merge branch 'master' into gooseberry

Constrain hair root vertices to their mesh location after applying tools.

Enforce hair constraints (constant segment length) after applying a tool.

Currently uses the same approach as old particle edit mode (rescale
hair segments from the root on). A more sophisticated approach using
least-square error minimization of the displacement could yield better
results.

Make sure tool input data is in object space.

Nicer vector math for mouse coordinates.
