In 20 pt staff This corresponds to the current value of blot diameter.
staff_line_thickness is .5 pt, and blot_diameter is .4 pt.

This is very odd.
If you use ljfour instead of ljfive it does not work at all (i.e. no roundings
at all)
Does anybody have an explanation of this?

Yes I think it is.
I agree that 600 dpi is too low, but on the other hand, it's what most people
use, afaik.

Well, I did some brute force testing, and found out that with blot_diameter# =
.45pt#; the corners got perfect (one pixel missing) on both ljfour and ljfive -
in 600dpi, and I hereby suggest to increases the blot_diameter to .45pt.

I agree.
But I still think that the feta-quarter rest is the most beautiful quarter rest
I have ever seen.
I have actually made a big A4 proof sheet of the quarter rest in mp, and it's
hanging in my livingroom (yes seriously, it is true).

Whatever.
