- as originally intended years ago, but never actually done.
- use 'foamPvCore' instead of 'vtkPVReaders' to avoid potential name
collisions with any 'vtk*' files and since we may reuse these
functions in other foam-paraview modules (not just readers).
STYLE: use same font size/colour for patch-names as for point-numbers
BUG: repair issue with single time-step
- paraview time-selector returns '0' as the requested time if there is
only one time step. However, if we have skipped the 0/ directory,
this single time step is likely a non-zero value.
- although this is not the final desired form, since it uses
individual pqPropertyWidget customizations (ie, ugly layout, too
many bits of code), but is an interesting intermediate solution
that may be useful in other contexts.
