[vtk-developers] Request: Make certain methods related to tick labels in vtkAxis virtual

[pdhahn]

Please make the following "generate" methods related to tick labels in
vtkAxis virtual so they can be overridden in a subclass:

GenerateSimpleLabel(), GenerateSprintfLabel(), GenerateLabelFormat(),
GenerateLogSpacedLinearTicks()

These methods all  can call this->TickLabels->InsertNextValue( ... ) with a
label that they create.

This would allow better control over tick label generation by
re-implementing these in a subclass that handles additional kinds of
"notation" and corresponding tick labels, as opposed to having to use the
custom tick labels mechanism. In particular, date-time (timestamp) tick
labels.
