thank you.

it is like Adam's arsd: a collection of random things. basically, 
when i need something for one of my projects, i'm going to 
steal/implement it "in-place" (i.e. in project source tree), and 
later i may see that implementation as a good thing to share 
between other projects. at this stage i'm doing some more work on 
it, and then moving it in IV. and even if it won't be shared 
between projects, i sometimes moving it to IV just to have it 
everything in one place. ;-)

i investigated the possibility of having IV as collection of DUB 
projects (again), and it is still too intrusive. alas. actually, 
i'd like to feature IV as a set of libraries with dependencies on 
code.dlang.org, so people can easily use 'em, but DUB isn't very 
tolerant to things that aren't done in "DUB way". i am really 
saddened by that, but i have no desire to work on DUB, neither to 
"dubify" my workflow.

i'm trying to help those who wants to use my code, tho. ;-) i'm 
usually available on IRC.


p.s. to keep it all somewhat on-topic: if someone wants to add 
more joint types, it is possible to take 'em from Chipmunk code, 
almost unmodified. Chipmunk is using basically the same 
integration scheme (preStep/applyImpulse), so you'd have to do 
some simple renamings (cpFloat -> VFloat, etc.), and replace 
Chipmunk's vector math with iv.vmath. i deliberately avoied doing 
that to keep the code small (and to not spoil the fun of turning 
something simple to something more powerful ;-).
