COMP: Fix compile error on Irix64-CC due to old style C++ scoping issue.

BUG: fixed bug in fragment program lighting for transforming world coordinate lighting parameters into local volume coordinate before executing fragment program

ENH: Fix for old CTest. Looks like old CTest did n ot read CTestCustom from the toplevel source directory

COMP: attempt to remove all the old hacks in the vtkMPEG2 encode lib. The library was using many hard-coded static/global vars, had dependencies to vtkImaging/vtkFiltering that need to be remove now that it is in VTK, and was not setup to be built as a DLL:
- remove all uses of the global ::vtkMPEG2WriterStr structure by passing the structure to all functions that require it.
- remove all refs in the lib to the global MPEG2_error by specifying a callback in the structure (and a calldata).
- add proper extern/__declspec macros so that it can compile as a DLL. This allow the removal of the VTK helper class that had to be in the same scope previously.
- remove all deps to other VTK classes by discarding the helper class.
- remove all deps to vtkImaging by coding the vertical flip manually.
- etc.

BUG: Automatic pwd/cwd path translation must check that the generated logical-to-physical mapping is correct by using realpath.

COMP: Fix subdirectory ordering to match library dependencies to help CMake 2.0 build VTK.  Update vtkmpeg2encode library to use VTK versioning and installation configuration.

BUG: VTKFTGL_SOURCE_DIR, VTKFTGL_BINARY_DIR, VTKFREETYPE_SOURCE_DIR, and VTKFREETYPE_BINARY_DIR are not set during the first CMake configure step.  Produce the paths in a way that works the first time.

COMP: Wrap all parallel cxx tests in IF(VTK_USE_DISPLAY) to avoid guaranteed test failures on dashboards that have VTK_USE_DISPLAY off. All of them use the display...
