Filter Operators

Operators that take an input and modify it.

Many of these are spatial transformations (scale, rotate, translate), which alter the coordinates that are used by their input operator.

Many of these can be used for various types of return types (SDFs, float/vector fields, etc). Some only support a limited set of return types.

Operators

	`adjustColor`	Adjust properties of color values, either directly on a field, or on the assigned surface color of an Sdf result.
	`applyTransform` beta
	`assignAttribute` beta
	`assignColor`	Assigns a surface color attribute to an SDF surface.

	`quadTreeRepeat` beta	Repeats space in a 2d grid where some cells are subdivided into smaller cells recursively.
	`quantizeCoords`	Quantize coordinates to a 3D grid, which is sort of like "voxelizing" the space.
