This patch adds paint symmetry support to Quadriflow. It bisects and mirrors the input and the output from the remesher to build the final mesh using the preserve boundary option.
This can be considered a new feature, but I think this is rather important to have for 2.81 because most of the new sculpt tools rely on topology symmetry to keep the symmetry of the sculpt. It is also an important performance improvement in Quadriflow because it only needs to process half of the mesh with half the resolution.
