STYLE: Added description.

This is a temporary fix for memory use in the Qt label render strategy.
The strategy caches all unique strings, and in the case of charts this
could be a large number of strings (hundreds of MBs). Until the label
render strategy is fixed the approach taken here is to delete the object
and create another one every 300 renders with text.

New function to get the number of axes in a chart, also renamed
GetNumberPlots to GetNumberOfPlots in order to be more consistent with
naming in other places.

BUG: Preserve topology and show frustum can not be combined because one says do not change the data type and the other says always make an unstructured grid to display the bounding box. Show frustum was for debugging originally, it should be replaced with a proper widget at some point and the option removed.

This was causing some issues on a Linux box for me, and we are not using
phonon directly. Restrict to just apple for now, where this was known to
cause problems.

processes when writing AMR. Fixed that.

ENH: cell volume is computed separately into cell array 'CellVolume', allowing one to use
ENH: vtkDataSetGradientPrecompute to compute cell volume.

COMP: add a missing case for vtkTypeUInt64 to the python wrapping parser. Thanks Brad King for the help!

BUG:Fixed blank image when the volume transform introduce some not orientation-preserving transformation.

The line plots cache a sorted array of points, instead of assuming the
points are sorted. This does cause duplication of the points, but allows
for a much faster binary search to be performed. Perhaps there should be
a cutoff on the size of the array to be cached.

Display a tooltip, showing the current value of the series under the
point. Currently working for vtkPlotLine, but any vtkPlot derived class
can implement the necessary virtual function.

Added in a new virtual for the plots, where the nearest point (to within
a supplied tolerance) will be returned. The vtkPlotLine class implements
this using the STL lower_bound binary search algorithm.

This API never made it into a release, and was mistakenly taken from the
3D equivalent. Removing before the branching/release.
