Issues about optical spacing

[Tomohiro Tatejima]

Hello all,

I encountered some issues related to optical spacing. One is like this:

\version "2.19.80"
{
  \override Staff.NoteSpacing.same-direction-correction = #2.5  % to
emphasize effects of optical correction
  c'2 a | c' b | c' c' | c' d' | c' e'
}

The output file is attached as example1.png.
There is a spacing increment between notes when the interval is 3 or
more, as you see in measure 5. Is this an intentional behavior?


One more issue about optical spacing is that this correction is
totally disabled when the rhythm interferes with others.

\version "2.19.80"
<< { c'8. 16 8. 16 }
   \new Staff
   {
     \override Staff.NoteSpacing.same-direction-correction = #2.5  %
to emphasize effects of optical correction
     r8 \tuplet 3/2 { a16 c' e' } r8 \tuplet 3/2 { e'16 c' a }
   }
>>

The output is example2.png.
Desired output is that notes in each tuplet are equally spaced.
Is it technically possible to implement this?


Sincerely,
Tomohiro Tatejima
