ruler snap adjustments
- when in wireframe mode: don't snap to faces, instead snap to the closest edge/vertex.
- when not in wireframe mode: snap to the front-most element (was a problem that it could snap to an edge/vert behind the face)
- reduce the distance for selecting ruler points, was too easy to accidentally drag a ruler.

fix [#35072] View name of 3Dview is clamped in Japanese
just increase size of string to allow for utf8 chars.

Fix #29932 Left Shift + Numpad 1,2,3 not Aligning to Active

Intermediate Shift+Key messages were resetting modifier flags.

Fix build error with scons + msvc, needs pthread include.

Fix two more high DPI / retina draw issues with running jobs in info header and
the node tree name in the node editor.

Fix #34806: rigid body world settings were not copied with a full scene copy.

Now copying a scene will also duplicate groups that consist entirely of objects
that are duplicated with the scene. The rigid body world will then also pointers
to these new groups.

Fix crash going to a scene with no camera, with an inactive 3D viewport space.

The regions of the space are stored in a different place depending if it is
active or if another space is in use. The code here was iterating over both
but it should be only one because the other might contain regions of another
space.

Fix rigid body world Solver Iterations not showing in UI and throwing python error.

minor fixes
- build with netbsd works again.
- select uv more/less was crashing when called outside image space.
- node RNA property update was crashing when not called in node space.

Fix #34714: cycles viewport render would restart when minimizing and unminimizing
a maximized Blender window in Ubuntu Unity. The window size would slightly change
as part of the unminimize effect.

Now cycles waits 0.2 seconds before restarting rendering after a viewport resize,
also a bit less flickery when changing the 3d view size in Blender itself.

Fix cycles build error, RNA C++ API did not properly handle output parameters.

Fix flickering black tiles in preview render, after viewport render commit, it's
nicer when the new preview draws over the old one.

The code was changed so that the render result is freed all the time because
freestyle manipulates render layers. Now it only does it when freestyle is
enabled so cycles and regular blender internal can still avoid it.

Fix blender internal preview rendering continuously restarting after recent
viewport render changes.

Actually was an older issue that would cause unnecessary preview render restarts
if the render result was not allocated before it was drawn. Now the render result
is being reallocated each time for freestyle which made the issue worse.

rna api function scene.ray_cast now returns the object and its matrix (incase its a dupli).

Fix #34783: smoke simulation crash when changing frame while preview rendering.

Added a mutex lock for smoke data access. The render was already working with a
copy of the volume data, so it's just a short lock to copy things and should not
block the UI much.

Fix #35068: bpy.ops.node.output_file_add_socket() now works on the active node
if there is no "node" in the context, for scripting convenience.

Fix for #34739 and #35060, avoid ambiguity in compositor viewer nodes.

The design changes coming with pynodes for the node editor allow editing multiple node groups or pinning. This is great for working on different node groups without switching between them all the time, but it causes a problem for viewer nodes: these nodes all write to the same Image data by design, causing access conflicts and in some cases memory corruption. This was not a problem before pynodes because the editor would only allow 1 edited node group at any time. With the new flexibility of node editors this restriction is gone.

In order to avoid concurrent write access to the viewer image buffer and resolve the ambiguity this patch adds an "active viewer key" to the scene->nodetree (added in bNodeTree instead of Scene due to otherwise circular DNA includes). This key identifies a specific node tree/group instance, which enables the compositor to selectively enable only 1 viewer node.

The active viewer key is switched when opening/closing node groups (push/pop on the snode->treepath stack) or when selecting a viewer node. This way only the "last edited" viewer will be active.

Eventually it would be nicer if each viewer had its own buffer per node space so one could actually compare viewers without switching. But that is a major redesign of viewer nodes and images, not a quick fix for bcon4 ...

Fix #35008: compositing nodes viewer border (ctrl + B) not working correct inside node groups.

allow to scale and rotate from edge/vertex slide.

fix for crash changing transform modes rotate/edge-slide/grab. setCustomPoints() assumed allocated member was big enough which wasnt the case when switching from rotate.
