Some PPC/Intel data file problems fixed

I fixed some endian issues in GRASS and GIS Libs. This includes:

  • GRASS stroked fonts (would cause Tcl scripts to have problems, as well as text display commands).
  • PROJ datum grid shift files (would cause failure of datum shifts for NAD datums).

These are now rebuilt at install-time from the source data so that they are correct for the install architecture (PPC or Intel).

NVIZ still has problems, on both PPC and Intel, it seems. NVIZ still crashes on Intel. But, while it runs on PPC, after the initial rasters and vectors added from the command, the file browsers get all twitchy and you can’t add other rasters or vectors to the display.
