This commit extends limit of ID and objects to 64 (it means 63 meaning
characters and 1 for zero-terminator). CustomData layers names are also
extended.
Changed DNA structures and all places where length constants were hardcoded.
All names which are "generating" from ID block should be limited by MAX_ID_NAME-2,
all non-id names now has got own define called MAX_NAME which should be used all
over for non-id names to make further name migration stuff easier.
All name fields in DNA now have comment with constant which corresponds to
hardcoded numeric value which should make it easier to further update this
limits or even switch to non-hardcoded values in DNA.
Special thanks to Campbell who helped figuring out some issues and helped a lot
in finding all cases where hardcoded valued were still used in code.
Both of forwards and backwards compatibility is stored with blender versions newer
than January 5, 2011. Older versions had issue with placing null-terminator to
DNA strings on file load which will lead to some unpredictable behavior or even
crashes.
comparing bmesh to trunk, mesh_calc_normals() in bmesh is a much more comprehensive function, calculating mpoly,mface normals, where trunk only calculated vertex normals.
renamed:
* mesh_calc_normals() --> mesh_calc_normals_mapping_ex
* mesh_calc_tessface_normals --> mesh_calc_normals_tessface() - only calculates normals from tessface
* added mesh_calc_normals() - only calculates normals from poltys
this way we can have mesh_calc_normals() remain fast for parts of the code which only need vertex normals to be updated.
only refactor, no func changes- didnt replace mesh_calc_normals_mapping_ex() with mesh_calc_normals() anywhere yet.
Notes:
- uses 'c' as toggle key in and out of angle snapping
(aka constrain) mode
- when in angle snapping mode, after first click, will
constrain line to nears 0, 45, or 90 degree line
- constraint is in screen space, not model space,
so will usually be used in axis aligned view
CTX_data_pointer_get_type(C, "object", &RNA_Object).data
with api call:
ED_object_context(C)
... since getting the context object is such a common operation.
Notes:
- only cuts through when the occlude geometry button is unpushed,
else the old behavior
- doesn't add points in middle of occluded faces yet, so will not
make partial cuts or hole cuts in occluded faces; for best
results, start and finish cuts completely outside the mesh
- also made slight improvement to behavior when starting cut
off the model
- a small refactor: added knife_add_to_vert_edges for code
used a number of times
inconsistent with similar functions & math notation:
mul_m4_m4m4(R, B, A) => mult_m4_m4m4(R, A, B)
mul_m3_m3m4(R, B, A) => mult_m3_m3m4(R, A, B)
For branch maintainers, it should be relatively simple to fix things manually,
it's also possible run this script after merging to do automatic replacement:

* even offset, uses same shell distance method as solidify to give even with beveled faces.
* distance offset, this is mostly for compatibility with the modifier in trunk which uses the bevel width as a distance rather then a percentage. at the moment this is awkward for the operator since it makes percent act differently where the 0-1 range doesnt make sense.
still need to bring back more options from trunks bevel modifier.
Return OPERATOR_FINISHED from select grouped operator in any case so
even if nothing were selected operator would be registered in redo panel
and threshold can be adjusted there.
Warning! Tesselation uvs or vcol data got out of sync, "had to reset!
This would happen on every editmode edit with UV's and wasn't too reassuring that blender was handling uvs/vcols correctly.
From looking into the problem I found that creating the undo mesh would act as if it was tessellating the existing mesh each time and complain that the data was out of sync, when infact the mesh was just created and being filled in.
Also, allocating uv and vcol customdata arrats for tessfaces isn't needed for undo mesh, so save some memory and dont allocate these in the first place.
