Use delimitershortfall and delimiterfactor for stretching vertical delimiters for SVG.
Fix a conflict with noReflows and mtextFontInherit.
Fix multiple problems with indentshift and indentalign in HTML-CSS and SVG output.  (Negative values not handled properly, shift not applied to centering, SVG not handling shift past edges well, percentage shifts now in relation to container, etc.)  Resolves issues #769 and #768.
Add an empty <mo> to nested <munderover> used for overline and friends to avoid being an embellished operator that gets movablelimits.  Resolves issue #490.
Fix the alignment function so that it handles overlapping on the left and right better, and so we don't have to do it in the linebreaking directly.
Use alignment function for mtable with labels as well.
fix min width of tables (em's inside are different from em's outside).
Get linebreaking size correct for zoom boxes, and do a better job of managing the width for full-width tables (only make the box as wide as necessary).  Resolves issue #834.
