For an extreme example, try on 99/4 for size. I'm not sure what
the highest possible numerator is without things getting this nasty.
I'm not bored enough to try points in between to try to pick the
highest number that doesn't cause the notation editor to render
16/4 doesn't seem to be working too well, but it doesn't actually
cause a screen full of gibberish. The spacing is all funky and
unpleasant, and the key signature (Ab) and time signature are
overlapping in an ugly way.
(I'm trying to enter something and I have no clue what time it's in.
I'm looking for a way to have the flexibility to keep futzing with
durations until I get the rhythm written out correctly, and then I
hope it will become obvious what the time is once I've done that.
I'm trying for a large enough numerator that I can quit worrying
about breaking things at bar lines that probably won't be bar lines
when I get through.)
BTW, these buttons in the time signature dialog (the up/down
buttons) really need some kind of extra handler code so you can
click and hold and keep spinning, like a spin box. Clicking 99 times
