First node is called Keying Screen (Add -> Matte -> Keying Screen) and it's
aimed to resolve issues with gradients on green screens by producing image
with gradient which is later used as an input for screen color in keying nodes.
This node gets motion tracks from given movie clip and trackign object and uses
them to define color and position of points of gradient: for position marker's
position on current frame is sued, for color average color of pattern area is
used.
Gradient is calculating in the following way:
- On first step voronoi diagram is creating for given tracks.
- On second step triangulation of this diagram happens by connecting sites
to edges which defines area this site belongs to.
- On third step gradient filling of this triangles happens. One of triangle
vertices is colored with average track color, two rest vertoces are colored
with average color between two neighbor sites. Current pixel's color in
triangle is calculating as linear combination of vertices colors and
barycentric coordinates of this pixel.
This node is implemented for both tile and legacy compositor systems.
Second node is basically a combination of several existing nodes to make keying
more straighforward and reduce spagetti mess in the compositor, but it also
ships some fresh approaches calculating matte which seems to be working better
for not actually green screens.
This node supports:
- Chroma preblur
- Dispilling
- Clip white/black
- Dilate/Erode
- Matte post blur
This node doesn't support chroma pre-blur for legacy compositor (yet).
There're still lots of stuff to be improved here, but this nodes night already
be used i think.

This patch also contains some currently unused code from color math module, but
it was used for tests and might be used for tests in the future. Think it's ok
to have it in branch at least.
* Made the new custom theme options a bit better and more compact.
* Added a few separators to better distinguish these settings from the actual node buttons.
For an detailed user-level description of new features see the following blogpost:
http://code.blender.org/index.php/2012/05/node-editing-tweaks/
TL;DR:
* Frame node gets more usable bounding-box behavior
* Node resizing has helpful mouse cursor indicators and works on all borders
* Node selection/active colors are themeable independently
* Customizable background colors for nodes (useful for frames visual
distinction).
Note: the problem of sockets translation remains (for all node types), currently they are unavailable from RNA, hence not detected by i18n tools, so only solution is to add N_() in all node sockets templates… yuck! Really have to fix this.
quite problematic in button layout
* Added first column with labels
* increased max size of node
* moved the start/end midtones to the bottom of the node
Displaying image layers with flattened names (render_layer.render_pass) can lead to extremely long socket lists, especially with older files that were used with distinct render layers before. In general the flattening of names would be preferable, but it needs a sensible way of limiting the number of displayed outputs. For now the render layer dropdown selection is the best option to ensure usability.

This operator still had some built-in assumptions about the connectivity of input/output sockets (1-to-n in all current node systems). For future node systems (e.g. flow-based particles) and for general customizable nodes the operator is now fully symmetric and supports all kinds of connectivity limits (1:1, 1:n, m:1, m:n).
The operator data can also store a list of node links as opposed to a single link now, so that multiple links can be redirected at once. Holding the CTRL key when clicking a socket, all links from/to that socket are detached and can be moved to a different socket. This is useful for quickly appending a node without moving every individual link.
--- Changes to File Output node ---
* Flat layer names in EXR multilayer files.
For a socket with name "AAA" the previous resulting EXR layer name would be "AAA.AAA", i.e. the render layer as well as render pass would use the socket name.
Now the "render_layer.render_pass" scheme is ignored in multilayer files, socket names are directly written to EXR layers (EXR layer name is "AAA" in this example). If sockets should have a notion of "render layer" this can still be achieved by explicitly adding a separator, e.g. "AAA.BBB". When loading such layers into a Blender Image struct, the name is interpreted as a "render_layer.render_pass" again (although the image node does not care about it, see below).
* Socket sub-paths (for singlelayer) or layer names (for multilayer) are stored in dedicated string variables in the socket storage data. This way the RNA can define precise string subtypes (PROP_FILEPATH) and length. The file/layer slots are defined as separate structs with own name properties in the RNA as well, so they can be used nicely with the list template.
* Ensure unique socket paths/layer names to prevent overwriting of files and layers respectively.
--- Changes to Image node ---
* Loading multilayer OpenEXR files has improved layer name splitting into render layer + render pass names now. This properly supports arbitrary EXR layer names now.
Example:
OpenEXR layer name: AAA.BBB.CCC
is split into
Render layer name: AAA.BBB
Render pass name: CCC
If the layer name has no '.' separators the render layer name is empty.
* Image node ignores the selected render layer in the image user data. Instead all existing layers are displayed at the same time by combining the render layer names with render pass names again, to reconstruct the original EXR layer name. This avoids the problem that render layers with empty name are not selectetable in the dropdown and allows using all image layers at the same time without duplicating the node.
This was originally reimplemented as part of the socket selection feature, but since selecting a socket necessarily also selected the owning node, it messes with the manual user selection of nodes too much (and doesn't add any additional usability).
