Support rendering math as svg in html and epub output

[xuhdev]

Rendering math as svg is pretty useful: the vector image would look much nicer than the png correspondence. Although MathJAX can be used for html, it (a) does not work in epub, (b) is heavy (takes time to load), (c) requires javascript.

I have a solution which I've implemented locally, which modifies pngmath to render math as svg images. The major part of the extension is pretty much the same, thus I would prefer to modify pngmath to support svg output. However, the name pngmath would no longer be appropriate. I have a few questions here, if they can be answered, I can make a proper PR:

• How about renaming pngmath to imgmath? Or simply not renaming (a bit confusing)?
• If renamed, how to deprecate the old name?
• The PR should be sent to master, is this correct?

Solving this issue also solves #1570

How about renaming pngmath to imgmath? Or simply not renaming (a bit confusing)?
If renamed, how to deprecate the old name?

To keep compatibility, it would be better adding imgmath as new extension.
And, pngmath should warn deprecated message on importing.

The PR should be sent to master, is this correct?

Yes, please!

@shimizukawa @birkenfeld What do you think?

Yes, no renames please. Renaming the default theme was painful enough :)

[shimizukawa]

+1 for no renaming :)
