Compared to previous implementation, the following has been changed: * Threshold: is now an absolute value. This allows a comparison with e.g. radii that are much larger than selected radius. This is also consistent with `CURVE_OT_select_similar` * Radius in world space is the average of the radius scaled in x, y and z directions * Since MetaBalls are symmetrical, rotation is only considered from 0 to π/2. So for example rotations of 90° and -90° are considered equal. This is also consistent with the way `CURVE_OT_select_similar` works. Fix/changes from committer (Dalai Felinto): * Drawing not updating after changes. (see original patch for details). Reviewers: dfelinto Differential Revision: https://developer.blender.org/D3895
