Fix SVG's mpadded container to not be removable, since the size no longer corresponds to the contents
Fixed an alignment problem when mpadded is used (and its contents has a removeable <g> contatining a <rect>)
Fix mtable align parameter to be the default (rather than center) when it is incorrectly specified (resolves error in issue #165)
Handle mode='display' attribute on math elements properly, now that is has been moved to a separate attr property internally
Make lspace and voffset handle bad unit better
Handle mixing of mathvariant with style settings better (but this does mean that variants without the proper weight or style will remain unchanged)
Fix font message for SVG output
Handle mixed mathvariant and styles in SVG output (like in HTML-CSS) and make explicit fontfamily, fontweight, or fontstyle (even inherited) override style setting.  Finally, handle numeric font-wieght (Opera converts bold that 700)
Handle conflicts between inherited mathvariant and fontfamily properly.  (Fixes problem with ms having default mathvariant='monospace' when fontfamily is specified).  Fix bold for stretched operators when weight is specified numerically.
In SVG output, remove blackness from HW when looking for delimiter (since the delimiter sizes don't include that).  Fixes problem with parens stretching when they should be their natural size (in some of Fred's tests).
Fix problem with handling of initial negative spaces when initialSpaceBug is true (Opera and IE).
Additional changes to fix STIX font problems in Safari (the NonUnicode fonts also needed to be adjusted).  Resolves issues #152 and #178.
Handle offsets within the fontdata-extra data in SVG output
Work around Opera's translation of font-weight:normal to font-weight:400
Make lspace and voffset handle bad unit better in SVG (corresponding correction to HTML-CSS is 6e8ff20e07eb79a128be7868f6c45ebb98e65ac0).  Resolves issue #191 for SVG
Improve linebreaking to work better when the equation doesn't have nesting to help group terms that shouldn't be broken.  Also make breaks at large spaces more desireable.
Prevent breaks right before a closing fence or right after an open fence.
Make mml2jax work better with IE namespaces (IE9 no longer seems to list the xmlns entries on the html element)
Move code that prevents numbers from being treated as a unit for super- and subscripts to the super- and subscript routines (instead of prefiltering for it).  Resolves issue #192.
Isolate MathJax images from page's float CSS
