2013-01-20	Update object bounding box during sculpt	Nicholas Bishop
	Fixes the sculpt object being incorrectly clipped during drawing due to an out-of-date bounding box making it seem that the object had gone outside the view. Added a BKE_pbvh function to get the top-level bounding box. In sculpt_flush_update(), where the PBVH bounds are updated, the result is copied to the object's bounding box. Fixes bug [#33790] projects.blender.org/tracker/?func=detail&aid=33790&group_id=9&atid=498
2012-12-30	Code cleanup: rename BLI_pbvh to BKE_pbvh	Nicholas Bishop

2012-12-30	Use GPU_Buffers to draw wireframe when in dynamic-topology sculpt mode	Nicholas Bishop
	This adds an override to the CDDM edge drawing function that switches to GPU_Buffers drawing for PBVHes of type PBVH_BMESH. Within the GPU_Buffers code, glPolygonMode() is used to draw lines instead of faces.
2012-12-30	Add dynamic topology support to the PBVH	Nicholas Bishop
	* Add BLI_pbvh_build_bmesh(), similar to the other PBVH builders but specialized for BMesh. Whereas the PBVH leaf nodes for mesh and grids only store a start-index and count into the primitive indices array, the BMesh version uses GHashes to store the full set of faces and vertices in leaf nodes * Update PBVH iterator to handle BMesh * Make some of the pbvh.c functions non-static so they can be used by the new pbvh_bmesh code * The BLI_pbvh_bmesh_update_topology() function is the main reason for adding BMesh support to the PBVH. This function is used during a sculpt stroke to dynamically collapse edges that are particular short and subdivide edges that are particularly long.
2012-12-30	Move layer displacements from SculptUndoNode to PBVHNode	Nicholas Bishop
	* This doesn't make much difference for regular mesh/multires sculpting, but for dynamic topology sculpting the undo stack isn't split up by PBVH nodes, so it's more convenient to store the layer data in PBVH nodes. * Note that the life cycle of the layer displacement data is unchanged -- it's only valid during a stroke with the layer brush, gets free'd when the undo step ends.
2012-12-30	Code cleanup: move PBVH/PBVHNode structs into new header file	Nicholas Bishop

2012-12-20	Change region drawing callbacks to work much closer to how blender manages ↵	Campbell Barton
	them internally. - yes, this does break scripts, but the api is marked experimental. ED_region_draw_cb_activate() adds a callback to a region type whereas the api made it look like the callback was being added to the region instance. Use a class method on bpy.types.Space to manage region drawing, eg. was: self._handle = context.region.callback_add(draw_callback_px, args, 'POST_PIXEL') is now: self._handle = bpy.types.SpaceView3D.draw_handler_add(draw_callback_px, args, 'WINDOW', 'POST_PIXEL')
2012-12-15	move pbvh into BKE, it used many BKE bad level includes.	Campbell Barton
	now blenlib/BLI doesn't depend on any blenkern/BKE functions, there are still some bad level includes but these are only to access G.background and the blender version define.
