issue 5312: Key cancellation glyph position inconsistent

file lily/key-signature-interface.cc

Using two intervals representing the "vertical skylines" of two
adjacent natural glyphs. This makes a better model of the actual
glyph shape than the original single point within an inverval.
Now we can distiguish between all three cases:
(1) no overlap -> no additional kerning needed
(2) just touching (overlap, but intesection length 0) -> kerning 0.15
(3) overlapping -> kerning 0.3

Case (2) is the new one that couldn't be handled before:
Just touching at the corners made the glyphs cling together.

Basically same interval technique as before, but I
renamed the Slices from
pos and overlap_pos
to
ht_right and last_ht_left.
Using quarter stave-spaces as to get a better (integer) resolution.

Hi everyone,Just noticed a bug in the default placement of the naturals when
key is changed.As you can see, the naturals aren't spaced correctly when
using the bass clef.I tried \Staff.override KeyCancellation.padding = #0.2,
but even with a larger padding, naturals aren't spaced uniformly

e.g

\version "2.19.81"

\new Staff {
      \key cis\major
      s1
      \key ces\major
      s
      \clef bass
      \key ces\major
      s^"problem"
      \key cis\major
      s \bar "|."
}
