developer_visualize: draws a solver's Vis tabs anywhere in the chain

A new node that reads the Vis tabs of the Developer Solver it points
at (default ../../.., the solver from inside its chain) and does the
drawing on the geometry passing through: Color tabs composited into
Cd with the solver's base, bounds, ramps, blends and opacities, and
the visualizer detail attribute set so the solver's marker
visualizers draw. The path is resolved on the node itself through a
hidden opfullpath parameter, since a relative path read from a wrangle
inside resolves against the wrangle.

Developer Solver's default chain now has one wired in before OUT, so
every node inside the chain can show the attributes as they are at
that point by taking the display flag, and the solver no longer
composites at its own output; it only adds the marker reference when
nothing in the chain has. Same version: the Vis tabs are unchanged,
and the change to what the output carries applies only to new
instances (an existing chain has no Visualize node until one is
added).
