Accidentals no longer tuck under/over previous notes
This is not a regression from 2.3.2 but it is a regression from where 3.0 was until shortly before release. This picture tells the story nicely:
There is no good reason for the space between before the accidental - it could be tucked under the previous note. It would have looked this way in 2.x, but this was actually one of the first major improvements implemented for 3.0 and was indeed one of the main reasons for moving to the "shape" system instead of the old spaceLw/space/Rw system of calculating segment distances.
Unfortunately, this broke when we added support for the old spaceLw/spaceRw in the form of addHorizontalSpacing(). This was needed in order to restore correct spacing for glissandi, and it also re-fixed the space allocation for ties. But now, we need to update the spaceLw/spaceRw calculations to not include the things that are already part of the chordrest shape. I'm on it. With any luck, this will be one of those fixes where simply removing some chunks of old code will make things work better.
