Swept capsule vs. triangle is pretty tricky and I haven't seen it documented
anywhere.  I implemented it by breaking down the problem into smaller
problems (line segment vs plane, sphere vs plane, circle vs line segment,
sphere vs line segment, sphere vs point).  I'm not sure how to do a swept
capsule that accounts for rotation other than relying on detecting the
collision due to penetration.  I'm wondering how many games actually use a
swept capsule instead of a series of spheres...
