[petsc-dev] handling any order of MatSetType() and MatSetSizes()

[Barry Smith]

   Shri has finished work on providing better support for setting the Mat type before setting the sizes. It no longer stores the MatCreate_XXX() pointer in the function table. It actually allocates the basic data structure and table of functions. Mat preallocate then completes the process using the size information provided.

   If you have any problems with this, please send email to petsc-dev
