New features:
* Bump mapping now works with SSS
* Texture Blur factor for SSS, see the documentation for details:

Work in progress for feedback:
Initial implementation of the "BSSRDF Importance Sampling" paper, which uses
a different importance sampling method. It gives better quality results in
many ways, with the availability of both Cubic and Gaussian falloff functions,
but also tends to be more noisy when using the progressive integrator and does
not give great results with some geometry. It works quite well for the
non-progressive integrator and is often less noisy there.
This code may still change a lot, so unless you're testing it may be best to
stick to the Compatible falloff function.
Skin test render and file that takes advantage of the gaussian falloff:

This commit includes all the changes made for plane tracker
in tomato branch.
Movie clip editor changes:
- Artist might create a plane track out of multiple point
tracks which belongs to the same track (minimum amount of
point tracks is 4, maximum is not actually limited).
When new plane track is added, it's getting "tracked"
across all point tracks, which makes it stick to the same
plane point tracks belong to.
- After plane track was added, it need to be manually adjusted
in a way it covers feature one might to mask/replace.
General transform tools (G, R, S) or sliding corners with
a mouse could be sued for this. Plane corner which
corresponds to left bottom image corner has got X/Y axis
on it (red is for X axis, green for Y).
- Re-adjusting plane corners makes plane to be "re-tracked"
for the frames sequence between current frame and next
and previous keyframes.
- Kayframes might be removed from the plane, using Shit-X
(Marker Delete) operator. However, currently manual
re-adjustment or "re-track" trigger is needed.
Compositor changes:
- Added new node called Plane Track Deform.
- User selects which plane track to use (for this he need
to select movie clip datablock, object and track names).
- Node gets an image input, which need to be warped into
the plane.
- Node outputs:
* Input image warped into the plane.
* Plane, rasterized to a mask.
Masking changes:
- Mask points might be parented to a plane track, which
makes this point deforming in a way as if it belongs
to the tracked plane.

of the scene user count. The node->id pointer for these nodes is now initialized in the respective init callbacks already. The explicit assignment and increment in the ED_node_composit_default is not
necessary and just adds an increment without checking previous values and decrementing them properly.
Note that the current system still leaves the scene with "fake" users (rlayer + composite nodes) which are actually part of the scene data itself. But that's design issue with the "local" node tree data
and doesn't do any real harm.
into the confined space of a node. However, in the side bar panel there is no reason to limit the buttons. In fact it is very helpful to have this UI available, otherwise users have to have an image
editor or (BI) texture buttons window next to the node editor to access these image details.
buffer antialiasing that was restored in 2.67 after it was missing in the new
compositor implementation.
This option tends to make results worse rather then better for Cycles renders,
but is useful for Blender internal. Their Z-buffers look quite different for
antialiasing, and I'd rather not change either.
Internally it was only invoke callback set for an
operator template. This invoke was setting such
properties as mouse_x and mouse_y and was calling
an exec function.
This meant that t seemed to be really easy to
use node.select operator from by giving a mouse
positions, but in fact it wasn't possible (because
it requires exec callback)
This commit sets operator's template exec callback,
which makes it possible using node.select from
python.
custom pynodes tree edited directly as library data would get a 0 user count on reload and subsequently not be saved. Now the node space follows the same pattern as the image space: the node tree(s) user
count gets incremented on file load and opening in the editor ensures a real user. This leads to 1 "unreal" user for the editor (dropped on reload), but seems to be the only viable solution atm.
node materials.
Area and region listener callbacks now get the screen and area pointers passed, so
they can do more fine grained checks to see if redraw is really needed, for example
depending on the 3D view drawtype.
* [#35724] Backdrop zoom can be set to a very small value, making the backdrop disapear.
There were checks in the drawnode that needed to be placed in the readfile.
The checks checked if the zoomlevel was 0.0, then it was defaulted to 1.0, but the zoomvalue had a minimum limit of 0.01, hence it did not work.
Moved the check to the readfile and checked for all values smaller then 0.02. These values are then reset to 1.0

proposal was to add another special init hack for the viewer node->id, but rather would do it right and so moved all the special init hacks for constant ID backpointers (Scene for RenderLayer, Composite,
Defocus, FileOutput and MovieClip for MovieClip, MovieDistortion and Stabilization nodes). These are now part of the local init callbacks functions of the appropriate nodes, using the new initfunc_api
callback which takes a Context pointer, so they have access to Scene.
to be done in cycles itself to keep compatibility for bytecode too.
Also fix broken button to compile OSL from the text editors, this got broken after
recent change to disable editing of library linked nodes.
having to go to the main area for changing socket values.
This patch should be considered a temporary solution. The Active Node panel is a horrible mess and needs to be split up and cleaned. It should probably be moved to python as well.
The drawinputfunc/drawoutputfunc callbacks in bNodeType are pretty much empty wrappers now and should be removed at some point. This per-node differentiation should rather be implemented as a specialized socket type if necessary. The only use case for this feature that remains is the file output node in compositor, which displays shortened file format info for each socket.
Issue was caused by ntreeUpdateTree calling for a ntree
which is not in G.main.
This lead to issues in ntreeVerifyNodes (which is called
from ntreeUpdateTree).
Made is so ntreeUpdateTree now accepts main as an argument.
Will work for the release, later we could either solve the
TODO mentioned in ntreeUpdateTree which will eliminate need
in main there or make it so context's main is used from all
over where ntreeUpdateTree is called (currently there're
still some usages of G.main).
The node link operator had a feature to automatically expose sockets in node groups when ctrl+shift+clicking on a node socket, which would create a node group input/output node. This was intended as a shortcut but conflicts with other features such as socket selection and viewer creation. It is also hardly necessary now that input/output nodes have an extension socket, which is much easier to use. Removed this expose functionality completely.
- 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.
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 ...
