Allow a title bar to be resized smaller than its width.

If a title bar becomes smaller than its width (the sum of widths of all its
icons) use an extension button to show hidden buttons.
Note that the title bar is as small as before but there is some space
between the title bar and the extension menu (when that appears).
It seems this is because the tool bar wants to be a certain size.

Added advanced color and opacity map controls

These controls are tables that display the scalar values and assigned
colors and opacities for the current color and opacity maps,
respectively. Colors and opacities are limited to the range [0, 1].
Colors are specified as RGB triplets. The first and last scalar values
cannot be modified through the table as these are set via different
controls.

In addition, tabular formatted text data can be pasted from the
clipboard using Ctrl-V. The tabular text data must be delimited with
an arbitrary amount of whitespace (no newlines allowed). Pasting
always begins from the upper left to the bottom right table cells.

vtkSESAMEReader is not used by Prism, we have new class vtkPrismSESAMEReader for
it.

BUG #14452: Fixed animation in pvbatch.

Animation scene didn't have the time-track setup by default in pvbatch/pvpython.
This was causing GoToLast/GoToFirst not work correctly in pvbatch/pvpython.
Fixed that.

Changes to allow setting particle tracer optimizations.

Before vtkParticleTracerBase assumed a non-changing multiblock
data structure and input seeds. VTK was updated to allow that to
be set while assuming the more general case of each of them not
being static. ParaView was modified to allow those settings to
be modified through servermanager.

Properly manage Widget toggling for Collaboration

In collaboration, a user can either be Master or participant.
Any participant is not allowed to edit any proxy property.
But once a participant became Master, all those disabled
Widgets should become enable again.
This is achieved by adding PV_MUST_BE_MASTER
properties to the pqProxyWidget base class.
Then the collaboration behavior will take care of the rest
automatically for you when the user status change.

Fix problem reading buffer from matplotlib

matplotlib.backends.backend_agg.FigureCanvasAgg.print_to_buffer()
prints an image to an old-style Python buffer object and ParaView was
using the API for the new-style Python buffer object. Serendipitously,
this works in Python 2.7.5 (on my development machine), but that is
not so on other Python versions. Switched to using the API for the
old-style buffer object and verified that it works with Python 2.7.2.

Fix tests failing on non-mpi builds.

These tests need MPI enabled since they use D3. Fixed that. They were failing
since D3 is no longer available in non-mpi builds.
