Line breaking inside shrink-wrap elements doesn't work well

[dpvc]

For elements that shrink-wrap their contents (like table cells or inline-block elements), the container width is measured as 0, and so line breaking can't be properly done.

Find a way to get the proper container width in that case (while still handling floating elements and other things that affect the width).

See issue #571, and also #1466.

The issue1478 branch of my fork of MathJax includes changes that gets the proper container width for math inside shrink-wrapped elements. It also makes all three output jax use the same mechanism for determining the container width.
