Marble and Speckle procedurals plus minor fixes #1407
Conversation
Adding Marble and Speckle nodedefs and nodegraphs. This includes a small utility node called util_specklenoise. Note that this is classified as an utility node rather than a new noise because it's just an existing noise with some multiply and range adjustments that is re-used multiple times in Marble and Speckle. It has no real use outside of that. Couple of more fixes 1) The legacy_noise procedural transform order has changed. Now rotate is execute before translate. (small node connection changes from line 440 to 510 in nodegraph file) 2) Small formatting/space changes to legacy_noise nodedef. (line 69 to 80)

Can we make these vector3 offset and vector3 rotation? It will reduce the number of uniforms, I guess we can't extract them for fractal later?

I matched the UI inputs, where we have 6 separate fields, 3 offsets and 3 rotations.
I'd like to revise one day, but I lack the knowledge. In RRT the transforms are a 4x4 matrix. Not sure where that comes from.
It's possible that when we will work on the converter for these, we realize the inputs are different. For now this is good for graph testing.

We probably need a readme in future to document the math used here.

The RRT code just say "taken from the Max code".
Basically the noise is multiplied by 1.65, clamped, and the range adjusted. No idea why.
