Functions
Chart Construction:
Faces and seams may only be added between ParamHandle::ParamHandle() and geometry::uv_parametrizer_construct_end. The pointers to co and uv are stored, rather than being copied. Vertices are implicitly created. In geometry::uv_parametrizer_construct_end the mesh will be split up according to the seams. The resulting charts must be manifold, connected and open (at least one boundary loop). The output will be written to the uv pointers.
void	blender::geometry::uv_parametrizer_aspect_ratio (ParamHandle *handle, float aspect_y)
void	blender::geometry::uv_prepare_pin_index (ParamHandle *handle, const int bmvertindex, const float uv[2])
ParamKey	blender::geometry::uv_find_pin_index (ParamHandle *handle, const int bmvertindex, const float uv[2])
void	blender::geometry::uv_parametrizer_face_add (ParamHandle *handle, const ParamKey key, const int nverts, const ParamKey *vkeys, const float **co, float **uv, const float *weight, const bool *pin, const bool *select)
void	blender::geometry::uv_parametrizer_edge_set_seam (ParamHandle *phandle, const ParamKey *vkeys)
void	blender::geometry::uv_parametrizer_construct_end (ParamHandle *phandle, bool fill_holes, bool topology_from_uvs, int *r_count_failed=nullptr)
SLIM:
begin: data is gathered into matrices and transferred to SLIM. solve: compute cheap initialization (if necessary) and refine iteratively. end: clean up.
void	blender::geometry::uv_parametrizer_slim_solve (ParamHandle *phandle, const ParamSlimOptions *slim_options, int *count_changed, int *count_failed)
void	blender::geometry::uv_parametrizer_slim_live_begin (ParamHandle *phandle, const ParamSlimOptions *slim_options)
void	blender::geometry::uv_parametrizer_slim_live_solve_iteration (ParamHandle *phandle)
void	blender::geometry::uv_parametrizer_slim_live_end (ParamHandle *phandle)
void	blender::geometry::uv_parametrizer_slim_stretch_iteration (ParamHandle *phandle, float blend)
bool	blender::geometry::uv_parametrizer_is_slim (const ParamHandle *phandle)
Least Squares Conformal Maps:
Charts with less than two pinned vertices are assigned two pins. LSCM is divided to three steps: Begin: compute matrix and its factorization (expensive). Solve using pinned coordinates (cheap). End: clean up. UV coordinates are allowed to change within begin/end, for quick re-solving.
void	blender::geometry::uv_parametrizer_lscm_begin (ParamHandle *handle, bool live, bool abf)
void	blender::geometry::uv_parametrizer_lscm_solve (ParamHandle *handle, int *count_changed, int *count_failed)
void	blender::geometry::uv_parametrizer_lscm_end (ParamHandle *handle)

void	blender::geometry::uv_parametrizer_stretch_end (ParamHandle *handle)
Packing
void	blender::geometry::uv_parametrizer_pack (ParamHandle *handle, float margin, bool do_rotate, bool ignore_pinned)
Average area for all charts
void	blender::geometry::uv_parametrizer_average (ParamHandle *handle, bool ignore_pinned, bool scale_uv, bool shear)
