add type checking for element buffers, there was nothing stopping python from passing any element type into an argument when in some cases only verts/edges/faces were expected.
now operator args define which types they support.
like it did before bmesh.
Neither method is perfect, ideally it should do smart detection of UV islands
but without that it's better to disable because it is more difficult to recover
from incorrectly merged UVs than ones that were not merged.
- the resulting selection is now correct
internal details
- bev_rebuild_polygon() now only rebuilds polygons that are attached to a bevel vertex (was rebuilding ALL).
... need to take care we don't leave faces pointing to removed geometry, so far this works fine.
- bev_rebuild_polygon() uses stack memory for <32 size ngons to reduce allocs.
- skip hash lookup when removing bevel verts (use tag instead).
When blending shape key, opening the popup didnt execute anything - making it so pressing a button would update the result even if the value didnt change.
- Rename 'mesh.select_nth' operator menu item 'Every N Number of Verts' to 'Checker Deselect',
since its not just de-selecting verts (works on edges and faces too) and the term 'checker' gives a better description of the result.
- Rename 'mesh.select_by_number_vertices' to 'mesh.select_face_by_sides', since this is a face selection tool, which wasnt obvious from its name.
also remove dissolve by type menu since the option has been removed from the operator and was giving an error.
* 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.
