This requires a forward declaration of v3f_t and changing din()
to take a v3f_t *.
The swab module needed updating to supply a pointer type and a
v3f_t definition.
This is being done so din.h users can have their own v3f
implementations. I might consolidate all the duplicated vector
code scattered throughout the libs and modules, but for now I'm
carrying on with the original intention of having modules be
largely self-contained. Though the introduction of libs like
ray and din has certainly violated that a bit already.

Mechanical change removing abbreviation for consistency
|

Mostly mechanical change, though threads.c needed some jiggering to
make the logical cpu id available to the worker threads.
Now render_fragment() can easily addresss per-cpu data created by
create_context().

Back in the day, there was no {create,destroy}_context(), so passing
num_cpus to just prepare_frame made sense. Modules then would
implicitly initialize themselves on the first prepare_frame() call
using a static initialized variable.
Since then things have been decomposed a bit for more sophisticated
(and cleaner) modules. It can be necessary to allocate per-cpu data
structures and the natural place to do that is @ create_context(). So
this commit wires that up.
A later commit will probably have to plumb a "current cpu" identifier
into the render_fragment() function. Because a per-cpu data structure
isn't particularly useful if you can't easily address it from within
your execution context.

This maps a different Z-slice through the noise field to each color
channel. The slices are moved up and down through the field over
time, and the size of the area each color samples is tweaked a bit
to make them less coherent with the noise field cells.
It could be improved, but I think the output is already neat enough
to be worth sharing.
