Take into account all rotations before comparing glyph positions

- it aims to fix #14497;
 - previously, only rotations with an angle 0, 90, 180 or 270 were taken into account;
 - so generalize to any angle but keep the fast path for 0, 90, ... because they're likely more common than anything else.
