[vtkusers] TimeValues attribute in vtkXMLReader limited to 4096 values

[Simon Praetorius]

Hi,

The VTK XML-files support an attribute of the primary element with the  
name "TimeValues" (see e.g. vtkXMLReader:693). This attribute is a  
space separated list of time values (as the name indicates). But  
unfortunately the number of values is restricted to 4096, i.e. an  
array of doubles is preallocated an then read by  
`vtkXMLDataElement->getVectorAttribute` that supports only double  
pointers as containers.

This restriction is quite harsh, I would say. I often have timeseries  
with about 10.000 timesteps and more.

Why is this implemented as an attribute instead of a block of values?  
There would not be this limitation, at least one could implement it  
without a limitation in the nr. of values.

Simon
