◆ can_rotate_before_pack_()

bool blender::geometry::PackIsland::can_rotate_before_pack_ ( const UVPackIsland_Params & params ) const

Check that rotation is allowed before packing, where the island may rotated to a desired orientation but not as part of packing. Needed for X/Y axis alignment to be supported.
