[Bf-blender-cvs] SVN commit: /data/svn/bf-blender [28869] trunk/blender/source/blender/ makesrna/intern/rna_space.c: access to 3d viewport location, distance and rotation.

[Campbell Barton]

Revision: 28869

Log Message:
-----------
access to 3d viewport location, distance and rotation.
- rotation must stay normalized (not enforced since it could break calculations)
- view_location is flipped internally.
