* Bullet's convex hull implementation is significantly more robust
than the one I implemented, as well as being faster.
* This fixes bug [#32864] "Convex Hull fails in some cases."
projects.blender.org/tracker/?func=detail&aid=32864&group_id=9&atid=498
That bug, and others like it, relate to the poor handling of
co-planar surfaces in the input. Pretty much any model that is
simple-subdivided a few times gave very bad results before, Bullet's
implementation handles this much better.
* In order to ensure a smooth transition, the Bullet output is
translated into the existing HullTriangle hash structure. This makes
it easy to ensure that the existing slot output stays the same; the
interactions between the slots are somewhat complicated, detangling
is a TODO.

- define array sizes for functions that take vectors.
- quiet some -Wshadow warnings.
- some copy/paste error in readfile.c made it set the same particle recalc flag twice.
When inset and bevel used the mouse input as a distance value, the change could be far too great when zoomed in, or far too small when zoomed out. Now get the pixel-size based on the center point of the selection.
* The symmetrize operation makes the input mesh elements symmetrical,
but unlike mirroring it only copies in one direction. The edges and
faces that cross the plane of symmetry are split as needed to
enforce symmetry.
* The symmetrize operator can be controlled with the "direction"
property, which combines the choices of symmetry plane and
positive-negative/negative-positive. The enum for this is
BMO_SymmDirection.
* Added menu items in the top-level Mesh menu and the WKEY specials
menu.

- vertex to screenspace projections were not checking for failure to project (vertex behind the view for eg).
- vertex screenspace 2d vectors were each malloc'd and added to own ghash, then fetched for each edge.
now just store a vertex aligned array and do index lookups.
- projections were done in global space, now do them in object space (avoids a matrix multiply).
- error cases were commented out and would fail silently, now report them to the operator.
- remove MAX_CUTS hard coded limit, dynamically allocate the mouse path.
- add missing free calls in error cases.
- make view3d project names more consistent.
- remove apply_project_float() its not needed.
- update comments referencing an old function name.
- move doxygen docs into the C file, prefer they are kept here to avoid getting out of sync with code.
border select. There was a fix before bmesh where it would require exactly two
vertices to be selected, but this was not ported over, and it also wasn't quite
correct.
This case should also work: click on two vertices, selected the path between
them, and then click on a 3rd vertex and select path, to extend the path further
from the 2nd to the 3rd vertex.
Now both use cases should work.
shape instead of just the difference/deltas applied by the source shape
Apparently this was a regression from that crept in during the BMesh merge. I've
just restored the pre-BMesh method, adapted for the BMesh style.
Also, removed a somewhat superfluous (?) copy at the end of each step (from co
back to sco). It didn't seem to be serving any purpose (i.e. we're not trying to
modify the source shape at all).
This commit adds "shift" and numtype to both Bevel and Inset mesh operators.
It also gets rid of the magicnumber used in NumInput to str operation (currently, 20 chars per element, now defined as NUM_STR_REP_LEN in ED_numinput.h).
