override minumum and maximum barlength

[Rob Canning]

hi

i am still working on a piece using proprtional notation - i now have it 
looking the way i want except for the minimum barlength being too short

- i would like it so even 16th notes are given plenty of space and all 
greater values are relative and proportional to that.

not sure how to achive this but i think maybe my answer is here:

http://lilypond.org/doc/v2.9/Documentation/user/lilypond-internals/SpacingSpanner#SpacingSpanner

though i'm not sure how to implement what i find there.

this is what i have atm:

%%% proportional  note spacing
\override SpacingSpanner #'uniform-stretching = ##t
\set Score.proportionalNotationDuration = #(ly:make-moment 1 24)

i'm not sure if this code is making much difference

what i really need is something like this psudo code

\override Bar #'bar-length = 50

i think setting a minumum and maximum barlength will fix things well 
enough for now...

cheers
