BUG #15053. Fixed issues when coloring with a no longer valid array.

When user was coloring using an array
and then he changed the pipeline such that the array is no longer
available, the "Color By" combo-box ended up showing "Solid Color",
though on underlying pipeline, the user's previous coloring selection is
indeed being used. This manifested as the color legend staying visible
even when the color-by widget was showing "Solid Color".

Since we don't want the widget to change the underlying pipeline's state
if an array disappears due to changes in the pipeline, we must update
the widget to continue to indicate that we're coloring with an array
and possible mark it saying that it's not present currently.
Furthermore, if the user switches the color array after that using the
UI, he should not be able to go back to the now no-longer-present array.

This fix addresses this. A no-longer-present array is now indicated in
the 'Color By' widget with a suffix "(?)". Also when the user selects
another array to color with, that entry will automatically disappear
from the 'Color By' combo-box.

HACK: Fix duplicate entries in Color By.

We sometimes end up with duplicate entries. Overcome it for now.
We need a proper fix in vtkSMArrayListDomain/vtkSMRepresentedArrayListDomain/
vtkPVDataInformation.  for now, just do this. To reproduce the problem,
skip the uniquifier check, and the load can.ex2, uncheck all blocks,
and check all sets. The color-by will have duplicated ObjectId,
SourceElementId, and SourceElementSide entries.

BUG #0011858. Fix unnecessary showing of scalar bar.

Don't show scalar bar when user changes color array selection if the
representation is currently not being shown in the view.

BUG #14921: Fixed scalar bar visibility from context menu.

Fixed updating of scalar bar visibility when coloring is selected using
the render-view context menu (similar to the COlor By toolbar).

BUG 14845: Added ability to reset color map.

Added ability to reset color map to XML defaults. The reset is not
naive, i.e. it will preserve the currently set color map data range.

Get ParaView working with the OpenGL2 backend

Some more work, it now compiles, links, and even renders some of the
geometry we want much more quickly than before (so long as simple
polygonal rendering is all you really want).
