Changeset 3818 for trunk/packages/vizservers/vtkvis/PolyData.h

Message:

Add colormode for PolyData?, by default color map if an active scalar field with
multiple components is present (color scalars). Add protocol for image/text3d
drawing components. Make 'color' synonym for 'ccolor' in protocol commands,
also accept 'ccolor' or 'constant' as colormode. Add experimental commands for
simple legend (no field info required), extended colormode for heightmap with
explicit range. Add fontconfig support (needs testing). Added code to remove
duplicate points from unstructured grids. Should probably be optional. Stack
trace on error (if WANT_TRACE is on) using VTK.
