This allows the sculpt brushes to work on meshes with multiple connected components as if they had only one connected component. These neighbors are calculated for each vertex using the minimum distance to a vertex that is in a different connected component.

bool SCULPT_handles_colors_report	(	const Object &	object,

Returns true if sculpt session can handle color attributes (pbvh->type() == bke::pbvh::Type::Mesh). If false an error message will be shown to the user. Operators should return OPERATOR_CANCELLED in this case.

NOTE: Does not check if a color attribute actually exists. Calling code must handle this itself; in most cases a call to BKE_sculpt_color_layer_create_if_needed() is sufficient.

Do a ray-cast in the tree to find the 3d brush location (This allows us to ignore the GL depth buffer) Returns 0 if the ray doesn't hit the mesh, non-zero otherwise.

If check_closest is true and the ray test fails a point closest to the ray will be found. If limit_closest_radius is true then the closest point will be tested against the active brush radius.
