Merge branch 'master' into depsgraph_refactor

Merge branch 'master' into soc-2013-paint

Aargh! More crash fixes!

Fix issue with curves crashing in texture paint mode. Also only do curve
manipulation if a curve brush is active (some modes actually use
transform for other things as well)

Add select all (A Key), scale (S Key) and rotate (R key) operations for mask points.
Also add extend selection with shift-select.

Reusable curves for the paint systems:

This commit includes the following:

* Per brush curve setting that allows setting a different curve per brush.
Those curves stay in memory and can be edited and reused accordingly.
To make sure that a curve is saved in a file users need to add a fake user,
similar to other datablocks.

* Interface while using curves is now non blocking. Users can pan, rotate,
and zoom the view while able to select and edit curve points as previously
in the GSOC branch.
Code internally uses the transform system. This needs some tweaking still
but it should be similar to the previous GSOC system. This may change
in the future to be more compatible with other curve systems
(ie enable choosing handle type etc.)

Fix issue with 'swimming' mask textures in 2d painting.

Revert "Basic DepsNode type in RNA and a root_node property in the Depsgraph."

This reverts commit 39b76f27bc4b8437bedb08dde46f968f81b8040f.

The depsgraph requires only a minimal RNA representation as a means for
debugging addons to access it and request debug dumps. Removing this
also avoids internal header includes.

Cluster graphviz output for generic component node types.

Tentative fixes for Pose Eval and related bone components and operations.

Handle the Pose Eval node type as a cluster in graphviz debug.

Renamed the scene depsgraph_rebuild filename argument to clarify that
this is for debugging only.

Support for debug graphviz output during the build process.

This uses two callbacks which can be set prior to rebuilding the
depsgraph. These will be called when nodes or relations are added, which
leaves the actual implementation up to the caller with minimal impact
on the depsgraph code.

These functions are stubs in non-debug modes, so they don't cause
overhead.

The Scene.depsgraph_rebuild() function implements this via an optional
filename argument. If this is specified it will dump build steps into a
sequence of files using _<N> suffixes with a running number N.

Fix for invalid FILENAME_MAX macro and missing includes in rna_depsgraph.

Make width of lines smaller.

* Use better OpenGL calls for curve drawing

* Draw handles for polylines/lines

Nicer font for graphviz debug output.

General support for subgraph nodes.
