CGNS, and ExtractSubsetWithSeed, is wireframe

CGNS is loading as a wireframe. Since we want to apply filters to CGNS that require an outside surface, these filters fail. Further, it can be confusing why these filters fail.

Please have all CGNS datasets load as solid.

Here is how to replicate the issue Watney had:

• Linux, remote server (64 ranks, but builtin server will show the problem - slowly...), master.
• Load Watney CGNS dataset. Should be 144 files. Turn on velocity_1, velocity_2 and velocity_3. Apply.
• Calculator. (Note - do NOT click in the formula box. #19387 (closed).). Formula will be velocity_1iHat+velocity_2jHat+velocity_3*kHat. Apply.
• ExtractSubsetWithSeed filter. Use 'p' key to make a cell selection.

Doesn't work, we need a surface. This is a bug.
