For some screen resolutions (e.g. mac book pro with retina display / double pixel resolution) the index viewer node's font size was too small to read and needed a scale factor of 2x. With this new setting the user can define the desired font scale in the SV preference settings. The default font scale is 1.0.

- made scale and xy multiplier pref settings generic to be used by multiple nodes
- add scale/multiplier adjustments to the texture viewer and easing node and update stethoscope node to use the same scale/multiplier

* updated tests to mk3

* lime mk3 docs

* Added Alpha and BW grayscale

* fixed grayscale

Profiling the edge generation indicated that it is a slow operation and since this edge list is generated over and over in various nodes it makes sense to cache it. Profiling of various nodes (generating edges) indicated a speedup of almost two orders of magnitude in generating the edges compared to the list comprehension counterpart (e.g. edges = [[i, i+1] for i in range(N)].

With the proposed optimization, the list of edges are stored in an edge cache (e.g. [[0,1], [1,2]... [n-1,n]] .. and the cache is extended as longer edge lists are requested/generated. Any call to get_edge_list will return a subset of this edge cache thus not having to re-generate the same list over and over.

Various nodes like the line, spiral, torus knot, ellipse etc, which that generate lines with linear list of edges can benefit substantially from this speedup.

To get the linear edge list use:
edges = get_edge_list(n)
returning: [[0, 1], [1, 2], ... , [n-1, n]]

To get the loop edge list use:
edges = get_edge_loop(n)
returning: [[0, 1], [1, 2], ... , [n-2, n-1], [n-1, 0]]

Optimize the linear edge list generation using caching

Port the same preference settings for xy/scale into the TVL node to fix the location and the size of the rendering.

The combinatoric operations implemented so far, based on itertools module are:

PRODUCT
PERMUTATION
COMBINATION

Add new Combinatorics node

- add 3 nodes: Quaternion In, Quaternion Out and Quaternion Math

Quaternion In:
Provides conversion from various quaternion components to quaternions (selectable via the mode option):
- components wxyz
- angle + axis
- euler angles
- matrix

Quaternion Out:
Provides conversion from quaterions to various quaternion components (selectable via the mode option):
- components wxyz
- angle + axis
- euler angles
- matrix

Quaternion Math:
Provides various quaternion arithmetic operations:

ADD
SUB
MULTIPLY
DIVIDE
ROTATE
DOT
DISTANCE
NEGATE
CONJUGATE
INVERT
NORMALIZE
SCALE
MAGNITUDE

Note: some operations take multiple quaternion inputs (input list grows as new sockets are connected), two quaternion inputs, single quaternion inputs, or quaternion + scalar input.

Add Quaternion nodes

…tures

The node will mix various other types (not just int/float) hence the name change.

Add various types to the MixInput node + new features & update UI

- add new types to mix: Vectors, Colors, Quaternions and Matrices.
- add SWAP feature to let the input A & B be swapped
- add MIRROR feature to mirror the interpolation factor
- add custom icon to MixInputs node
- relocate old MixNumbers node to old nodes
- update documentation

Restructure MixNumber into MixInputs node + add new input types and features

…rmalize to QOUT

Scalar-Vector is the same as WXYZ except that the input/output is provided as scalar W + vector (X,Y,Z). This is to help with the work-flow when quaternions are regarded as a (s,v) pair.

note: The Scalar-Vector is different thant Axis-Angle mode as for this mode the quaternion is Q = cos(a/2) + sin(a/2) * vector(x,y,z)

Matrix() from tree_generator.py

Added Deformation Node to master

Committing straight to master because i screw it :D (to fix it as fast as possible)

removed ready function and integrate its functionality to the process function

Added Path Length Node

The node allows to connect multiple mesh inputs (verts/edges/polys) and to select one of them to output. Useful for changing the input mesh model to be processed by a node tree.

New input sockets are added as new meshes are connected to allow the next mesh (verts/edges/polys) to be connected.

New Mesh Switch node

I accidentally rearranged code last minute before merging and caused an "variable access before defined" bug :) oops. This update fixes it.

This node allows switching among an arbitrary number of sets of any type of inputs connected to the node.

The node is essentially a generalization of the MeshSwitch node allowing any input types (not just verts/polyEdge) along with additional features:

- variable input set size
- keeps prior connections when changing the set size
- add separators between input sets
- add distinct labels to input sets (greek/latin letters)
- vectorizes the selected parameters (generates multiple output sets if selected gets an array of integers)

- New SeparatorSocket was also added to the set of socket types to help with the UI socket visual separation (e.g. group multiple socket into sets).

- New macro was added to allow to auto connect multiple selected nodes to the input swith node (via "> sw")

Add new Input Switch node and "switch" macros

- optimization
