[Paraview] XDMF Bug (Hard-coded drive letter C:)

[Ken Sheldon]

It appears ParaView uses the wrong drive letter when writing or reading HDF5 files via XDMF.

Steps to reproduce:
Start ParaView (I am using Version 4.2.0 64 Bit for Windows 7 64-bit)
>From the menu, select  Sources --> Plane
Set X Resolution 10
Set Y Resolution 10
Apply
File --> Save Data
  File format Xdmf data file
  File name D:\SAMPLE.XMF

Open the XMF file in a text editor.
Bug 1: The file refers to D:/SAMPLE.h5 .   However, there is no such file.  The HDF5 file is C:\SAMPLE.H5.

Bug 2: Reset the ParaView session and open the file D:\SAMPLE.XMF.  Apply. The data loads properly, although the XMF file refers to D:/SAMPLE.h5, which does not exist.

Bug 2.1: Reset the ParaView session. Move the file SAMPLE.H5 to D:\  (The directory referenced in D:\SAMPLE.XMF) In Paraview, select File --> Open SAMPLE.XMF.  Apply.

The program displays the Output Messages window with the following error message:
