Introducing Keyframe editor

This version introduces a new feature: animations via keyframes.

Those can be created via the node js/keyframes, which will store the animations.

And since everything in Polygonjs is procedural, animations will be equally procedural. This means that, unlike in most other 3D apps, animations are not created for a specific object. They are created in a parameter, which can then be linked to any other parameter.

In addition to that, keyframes are not only used for animations. They can be used for modelling, via the sop/objectBuilder and sop/pointBuilder nodes. This helps remapping any input attribute to another data. You could for instance take the position and remap that to the color, with any custom curve you like. And that's where the combinations are infinite.

New Nodes

• sop/objectBuilder: Allows editing objects using all the js nodes.
• sop/pointBuilder: Allows editing geometries using all the js nodes.
• rop/pathtracingRenderer: Creates photorealistic renders of your scene.
• js/keyframes: See Keyframe editor above.
• js/hsvToRgb: Adds color conversion to the js nodes.

Improvements

• sop/polywire: the shape created by the polywire is now smoother.
• mat/raymarchingBuilder: lighting model improved.

Bug Fixes

• gl/fractalMandelbrot: the fractal was previously not working outside of the mat/raymarchingBuilder.
