Replaced unified extrude edges/faces code (the stuff specificaly for edges/faces,extrudeflag_edgess, not the entire extrude system) with a bmesh version. This stress-tested the operator api, and I had to code some new stuff,including: * An api to iterate over Mapping slots and array slots. It's modeled after the normal iterator api. * The ability to copy mapping slots. * More mapping functions. * In addition to being able to flag elements in a buffer, you can now unflag them (much clearer then passing in ~flag I think). The extrude edge/faces code has multiple layers. At the top level is a funtion in editmesh_lib.c, which takes care of selection, handles mirror modifiers, etc. It calls the extrude operator, which in turns calls split, which calls dupe/del. Note that split needed a slot to exclude things from being deleting (e.g. when extruding a single isolated face). The basic idea (reflected in original design of split/dupe/del by Briggs) is to use the split function to do the heavy work of extrude. split spits out new geometry and mappings from boundary edges, for extrude (it should also spit out other mappings, but that's for later). Briggs: you may want to look over this, hopefully I didn't do anything too evil. I probably should spend some time going over the 2.5 mesh operators and cleaning them up, splitting ones that need splitting, etc, and in general getting them to work properly.

extrude handles loop customdata properly, also added a BM_Face_CopyShared function to copy loop customdata in a face from adjacent faces. it's not used (didn't work in this case) but it seemed fairly useful. may remove if it turns out to not be necassary.

split dissolve_disk into dissolve_vert dissolve_disk as agreed. also made dissolve vert bmop use the error api, and put in some code to report it to the user in the xkey ui code. I'm not sure how this should work; I don't think we can have utility code in bmesh/ for reporting errors to the user, so it'll have to go in editors/mesh somewhere.

Printf-style method of calling operations now take a modified format string, like so: [opname] [slotname]=%[format code] Before it was relying on the input format codes being in the same proper order as the slots, which seemed like a potential maintainance nightmare to me. Also the flags for creating buffers from bmop flags or header flags, now support additional modifiers for combining vert/edge/face inputs. E.g. %hfvef would accept all geometry with a header flag, and %fef would accept edges and faces with a certain bmop flag set. Example from the UI code: if (!EDBM_CallOpf(em, op, "del geom=%hf context=%d", BM_SELECT, DEL_ONLYFACES)) return OPERATOR_CANCELLED; (remember EDBM_CallOpf is the UI wrapper for this that does conversion, error reporting, etc). On todo is cleaning up/splitting bmesh_operators.h, since it's kindof a mesh right now. I'm thinking of adding the slot names in comments next to the slot ids, but I definitely would have to clean up bmesh_operators.h first, or it'd just be too chaotic for me. BTW, the operator API should now have enough meta info to wrap with a scripting language, not that it matters since that's not happening till much much later. Also hopefully corrected some SConscripts, fix mostly provided by Elia Sarti, though I also copied some SConscripts from 2.5 (not sure if doing so was especially helpful). Finally, I refactored a few places to use the new operator calling api, as an example of how this is beneficial.

At the top level is a funtion in editmesh_lib.c, which takes care of selection, handles mirror modifiers, etc. It calls the extrude operator, which in turns calls split, which calls dupe/del. Note that split needed a slot to exclude things from being deleting (e.g. when extruding a single isolated face). The basic idea (reflected in original design of split/dupe/del by Briggs) is to use the split function to do the heavy work of extrude. split spits out new geometry and mappings from boundary edges, for extrude (it should also spit out other mappings, but that's for later). Briggs: you may want to look over this, hopefully I didn't do anything too evil. I probably should spend some time going over the 2.5 mesh operators and cleaning them up, splitting ones that need splitting, etc, and in general getting them to work properly.

newedge = BMO_IterMapVal(&siter);
newedge = *(BMEdge**)newedge;
connect verts now does geometric tests to perform valid splits. it also supports multiple splits in a face, going around the face boundary in a loop and performing splits.

extrude uses dupe/delete rather then split, and it detects when to not delete geometry (though this could be smarter in the future). also BMO_pop had two lines out of order, which was causing flags layer to not always be freed when they should.

Replaced unified extrude edges/faces code (the stuff specificaly for edges/faces,extrudeflag_edgess, not the entire extrude system) with a bmesh version. This stress-tested the operator api, and I had to code some new stuff,including: * An api to iterate over Mapping slots and array slots. It's modeled after the normal iterator api. * The ability to copy mapping slots. * More mapping functions. * In addition to being able to flag elements in a buffer, you can now unflag them (much clearer then passing in ~flag I think).

//not sure what to do about example face, pass NULL for now.
f = BM_Make_Quadtriangle(bm, verts, NULL, 4, NULL, 0);
extrude handles loop customdata properly, also added a BM_Face_CopyShared function to copy loop customdata in a face from adjacent faces. it's not used (didn't work in this case) but it seemed fairly useful. may remove if it turns out to not be necassary.
