This is in preparation for bug fixing and cleanup related to tracking
of bmface and is_space state variables. And makes it more likely
to avoid bugs in future where some part of state is copied but not all.
Sometimes split would fail to make a face - make sure it doesn't
crash if that happens.
Chain finding code for holes would sometimes go back to same
vertex on the face, which causes problems, so fixe that.
Also, disallowed a cut that starts at a vertex or edge and
cycles back to that same point in a face - this would make
a face with a repeated vertex, which may not be handled by
the rest of the system properly.
Should resolve compilation error on some platforms when using linux and
compilation error of libmv on FreeBSB.
It was a regression caused by not applied changes on config_linux.h
and some changes made to utilities.cc were also occasionally missed.
- edgebisect bmesh operator used uninialized beauty field.
- BLI_join_dirfile could read from before the string bounds when passed an empty dir string.
- pransform could use an uninitialized projected coordinate (unlikely but possible)
- RNA_property_path_from_ID_check would compare against an uninitialized pointer when the path wasn't found.
also have bmesh walker use BM_edge_other_vert() utility function.
This version of libmv includes new gflags and glog libraries which makes
it possible to compile libmv with clang compiler.
Also remove code from CMakeLists which was disabling libmv if using clang.
Tested on linux with gcc-4.6 and clang-3.0, windows cmake+msvc and scons+mingw.
Could be some issues with other platforms/build system which shall be simple to resolve.
- moved mesh conversion functions into their own file.
bmesh py api:
- can now create a new empty bmesh without first creating mesh data.
- added function to copy bmesh data back to a mesh.
- bmesh.from_mesh() can now get a mesh which isnt in editmode.
World Context:
* Made world id block wider
* Don't show texture user when Cycles engine is used
Other:
* Change Dopesheet > DopeSheet in User Preferences Theme section for consistency.
* Hide Modifier and Contraint Panel header, this gives a bit space.
As it's the only panel in these context tabs it does not make sense to close them anyways.
This is called when adding a multiries modifier. BMesh MDisps have
only one loop's displacements rather than a full face's, so don't
multiply by number of corners here.
