Bring back some old scanfill code to handle tesselating polys with some zero-length edges. This code used to cause #4544 but I haven't been able to recreate that now, so I'm going to revive the old code and if #4544 does come back, we'll have to fix it some other way I guess (or come up with a better solution for zero-length edges in polys).
- replace "size= 4*( (size+3)/4 );" with "size = (size + 3 ) & ~3;"
- split new_mem_element into 2 functions, one to reset, another to allocate so allocating isnt checking to reset each time.
Made the new "superknife" tool much stabler
then it was, though a few minor quirks remain.
Rather then the shortest-distance-in-graph method
I was using to rebuild the mesh post-knife I
reworked it to build a triangulation instead,
then merge the triangles into the right correct
faces.
Most likely will not compile for others, I'd appreciate any build errors
and missing files reports (I can never seem to get everything committed
and all the build systems working without help).
Porting over the sculpt/multires tools was a breeze,
thanks goes to brecht for a design that didn't exclude
ngons and was easy to port.
Note that I've not tested externally-backed multires
file support yet. Also, I still need to write version
patch code for some cases.
Some notes:
* Like trunk, topological changes don't update multires right,
so e.g. subdivide will duplicate multires data on the new faces,
instead of subdividing it.
* If you set the debug value (ctrl-alt-d) to 1 it'll turn on
my experiments in speeding up sculpting on higher-res multires
meshes (but note it makes partial redraw not completely accurate).
* There's a bug where you have to go through editmode to get out
of sculpt mode, not sure if I inherited or created this myself.
* added renamed files in revision 25337
* renamed BLI_util.h -> BLI_path_util.h for consistency
* cleanup of #includes: removed BLI_blenlib.h in favour of direct includes of the needed headerfiles in a few places.
* removed debug print in sequencer.c
* added missing include in blenkernel/blender.c -> bad dependency, needs to be fixed still
* Convert all code to use new functions.
* Branch maintainers may want to skip this commit, and run this
conversion script instead, if they use a lot of math functions
in new code:

The 'edge fill' code failed on filling tiny small polygons. It has a limit
check for double points, which was hardcoded set to 0.0003.
That is (commented in code too) a weak part. Better would be to define a
bounding box first, and then derive the limit from that.
Further, the edge fill code uses blender EditEdge data, which fails when
the filling code removes edges. Certainly a topic to work on once, this
code is from the 80ies!
without initialization.

This line I don't understand...
