Old bevel 'Clamp overlap' code was very naive: just limit amount
to half edge length. This uses more accurate (but not perfect)
calculations for the max amount before (many) geometry collisions
happen. This is not a backward compatible change - meshes that
have modifiers with 'Clamp overlap' will likely have larger allowed
bevel widths now. But that can be fixed by turning off clamp overlap
and setting the amount to the desired value.
faces.
This was requested by script writers. Especially needed if beveling
wire edges with vertex_only.
Should be backward compatible as just adds two new keys to returned
dict in python ('edges' and 'verts').
Note: the angle in bug isn't really reflex - using the vertex normal
for this test isn't always right, but usually is. At any rate,
shouldn't try to put vertex on edge between if a reflex angle.
The mesh interpolation code had an edge case where one of two
adjacent edges to a vertex has 0 length. This caused an assert
failure indexing the vertex mesh for splash Blenderman.blend.
Use expanded names for bmesh primitive operations
(urmv jvke semv jfke).
Use 'bmesh_kernel_' prefix,
these functions aren't intended for wide use so favor readability.
Remove BM_face_vert_separate,
it wasn't used and only skipped step of finding correct loop of face.
Please **DO NOT** add changes from master when it's totally uneeded!
Changes to BLI_ area most certainly shall *always* be done in master,
there is absolutely no point in adding more diff between the two
branches than needed, will only makes merging more cumbersome!

This is the same issue as was fixed with T39486: the adjustment pass
that tries to equalize different widths at either end of an edge
sometimes causes the widths to get bigger and bigger.
The previous fix was to let "clamp_overlap" do double duty as a way
to limit this behavior. But clearly this is undiscoverable, as the
current bug report shows. So I put in an "auto-limiting" mode that
detects when adjustments are going crazy and then acts as if
clamp_overlap were set.
The reason we can't always act as if clamp_overlap is set is that
certain models (e.g., Bent_test in regression tests) look bad if
that is enabled.
Just return the face or NULL, like BM_edge_exists(),
Also for BM_face_exists_overlap & bm_face_exists_tri_from_loop_vert.
No functional changes.
Old code did some partial overlap checks where this made some sense,
but it's since been removed.
For simple cases bitmasks were OK, but didnt work for vert/edge, vert/edge tests.
Tag verts instead, makes logic easier to follow and gives minor speedup.
