Added to existing scn.objects
scn.objects.active (get/set the active object for the scene)
scn.objects.selected - an iterator that only uses selected objects
scn.objects.context - an iterator on objects in the user context (visible in the current 3d views layer and selected)
These are the same type as scn.objects but .add() .remove() .new() .active etc raise errors. so scn.objects.selected.add() will raise an error.
Made nested loops possible with scn.objects, metaball.elements and ob.modifiers, by initializing the iter value as NULL and creating copys of the pyobject when _getIter() is called if ->iter is not NULL.
This is how pythons xrange() works.
applied patch #4998 (array count), as well as adding other array settings, updated documentation as well.
added EXPP_setVec3Clamped() as a way to set a vector from getset attrs (used with array offset and scale)
Moved .up() and .down() methods from Modifier API to Modifier sequence
API (also renamed them to moveUp() and moveDown() ). Locating methods
which modify the "parent" structure in objects didn't seem consistent.
All settings through Blender.Modifier.Settings
see the epydocs
Also added some error checking to fix some possible segfaults.
Added more epydocs
Modifiers API should be stable enough to use now, though give it a bit of time for testing.
More Modifier API changes:
* add Blender.Modifier.Settings dict with constants for modifier types
* add mod.type attribute, which returns type of the Modifier
* add some internal consistency checks in ModSeq_remove
