Add support for negative/descending time values.

This issue was created automatically from an original Mantis Issue. Further discussion may take place here.


Add support for negative/descending time values.

From user:

Using geological time dependent data. Geological time dependent data are represented by positive numbers in million of years going from the past time to the present time using a descending order (e.g. 93 90 75 39 5.4 0). The example below shows how we can load this kind of data in ParaView. As you can see we had to associate to the time index 0 time step -93, to the time index 1 time step -90 and so on. So we need to set negative time steps in order to fit the ParaView logic used to animate time dependent data from past to present time (times must be stored in ascending order). What we would like to have is the possibility to use positive time step values (93 90 75 39 5.4 0) using a descending order and play animation starting from 93 My to 0 My.

Same problem is present for readers that support file series, where again ParaView logic works considering time in ascending order.
