Cleanup: de-duplicate playanim matrix

Fix Smoke UI property: Low resolution values are needed for pyroclastic smoke effects.
Example values for such an effects are resolution = 10 and high resolution = 5.

Patch by nudelZ

Smooth vertex: User request: tweak hard min/max smoothness.

Keep soft min/max to usual values, but allow artists to play with strange values
if they really want it.

Freestyle: New line style options for sorting and chain selection.

The following two sort keys are added for sorting chains.

* Projected X - Sort by the projected X value in the image coordinate system.
* Projected Y - Sort by the projected Y value in the image coordinate system.

A new line style option for the selection of first N chains is also added.

Moreover, the chain sorting and chain selection operations are now executed
in this order instead of the reverse order used previously. The UI has also
changed accordingly. This functional change is backward compatible and
won't result in visual differences.

Freestyle: Fix for a typo in the definition of NotBP1D.

This is a safe fix for a regression from 2.71, so should be back ported to 2.72.

Cycles: Filter Shader and Output nodes to their respective object/world node tree.

Some nodes only work in certain node trees, so don't show them in the Add Node menu when this is the case.
This can probably be expanded to Input Nodes too, but need to double check some cases here still.

Fix for duplicate member in UserDef from own commit (merge mistake).

Support for "virtual pixelsize" on 4k screens.

On 4k devices the default pixel size leads to tiny OpenGL drawing
that is hardly usable without doubling the DPI. The retina system
on OSX aims to alleviate this problem by introducing a general 2x
pixel size.

No equivalent feature exists on other platforms so far. However,
to emulate the effect this patch introduces a "virtual" pixel size
factor for OpenGL drawing.

Note that the user currently has to enable this manually by selecting
the "Virtual Pixel Mode" in the user preferences (defaults to native).
All windows of a Blender instance share the same virtual pixel size as well.
It may be possible to handle this on a per-window basis and automate
the selection somewhat (if enabled by the user), so working with
multiple screens becomes more convenient, but technical limitations
make this a bit difficult (on X11 with nvidia drivers the actual screen size
is not reported correctly).

Fix T42026: Unit scale affects camera focal length.

Not a regression, yet maybe simple/safe enough for 2.72?

Fix compilation on GCC (good old mixed declaration and code).

Style cleanup

fix T42022 Attempt to export empty set of objects resulted in an exception

Fix T42018: Crash when displaying beveled poly-curves with spline bevfac mapping

This fix is for 2.72.

Use native float math functions for MSVC12

`double` surrogates are slow (e.g. pow is 2x slower than powf), and MSVC12
supports fp-math functions from C99.

Libmv: update ceres to latest upstream version

This brings faster BlockRandomAccessSparseMatrix::SymmetricRightMultiply.

Blend modes: fix array length being too short

Reviewers: psy-fi

Libmv: Enable explicit Schur complement matrix by default

Gives up to 2x speed up of camera solving process in average scene.
In the really huge one it might be slower, but that we need to investigate.

Libmv: Update Ceres to the latest upstream version

Mainly to let ITERATIVE_SCHUR use an explicit Schur Complement matrix.

Fix BI viewport render crash happening with zero render border area

This is better to be backported to the 2.72.

Cleanup: style
