Merged

https://svn.blender.org/svnroot/bf-blender/branches/soc-2008-mxcurioni (r22789) and
https://svn.blender.org/svnroot/bf-blender/trunk/blender (r23338)
with the "Ignore ancestry" and "Ignore line endings" options enabled (using
TortoiseSVN on Windows).

After the merge operation, all changes (i.e., deletion) in source/blender/freestyle/
were reverted in order to keep the primary source tree of the Freestyle renderer.
