[svn-r5305]

Purpose:
    user reported a bug on h5 to gif tool
Description:
    h5 to gif did not read an HDF5 image correctly
Solution:
    updated the program so that it reads the updated HDF5 image format to the latest specification
    the debug version of MSVC was giving a failure on the write of the GIF file,
    regarding the GIF file pointer
    this write error is eliminated declaring that pointer a global variable
    there is still an applicattion error on the exit of the program, only on the debug version of MSVC



Platforms tested:
    w2000
