Prevent disappearing fraction lines. (#931)

Browse Source 
* Prevent disappearing fraction lines.

Set a CSS min-height that will ensure that fraction lines will display at least one screen pixel.

Addresses issues #824 and #916.

* Change from dppx to dpi

Change the break point spec from 2dppx to 192dpi. They mean the same thing. I'm making the change because IE supports dpi but not dppx.
