These readers display the epub decently well and render MathML. The "best" ones also resize fences (parentheses, brackets, etc) for large arguments.
Note that these haven't been updated since adding mover and munder to the MathML tests.
The overall goal is to use https://github.com/brucemiller/LaTeXML to convet https://github.com/teepeemm/APEXCalculusLT_Source to an epub. Some epub readers are less useful than others for reading the resulting file. The goal of this repository is to track what epub readers don't work and why, and to determine what shortcomings I can work around. For our purposes, "Good enough" and "OK" means the extent to which we're able to work around any problems.
Compile the epub using perl minimalEpub.pl epubSupport, and view the resulting epubSupport.epub with various operating systems and apps. We collect the results here.
In order to be good enough, the epub reader needs to use stylesheets, make a stab at rendering MathML, not have grevious mistakes, and not require a login.

Notes:
- Freda: white on black background except MathML is reversed; fence sizing ok, simplest
<mpadded>still has error.
The most common MathML errors are not resizing the fences (contributes 1 error) and allowing <mpadded width="-1.7pt"> (which comes from \!) to swallow its contents (contributes 2 errors). If a viewer has no comment on why it missed 1, 2, or 3 points for MathML, it's because of some combination of those two errors.
