## Default PNG rendering broken

This [1] edit broke the default layout. It's the PNG rendering which is broken with message:
Failed to parse (PNG conversion failed; check for correct installation of latex and dvipng (or dvips + gs + convert)): \begin{pmatrix} \textrm{John} & \textrm{likes} & \textrm{to} & \textrm{watch} & \textrm{movies} & \textrm{also} & \textrm{football} & \textrm{games} & \textrm{Mary} & \textrm{too} & \textrm{was} & \textrm{his} & \textrm{first} & \textrm{love} \\ 1 & 2 & 1 & 1 & 2 & 0 & 0 & 0 & 1 & 1 & 0 & 0 & 0 & 0 \\ 1 & 1 & 1 & 1 & 0 & 1 & 1 & 1 & 0 & 0 & 0 & 0 & 0 & 0 \\ 0 & 0 & 0 & 0 & 0 & 0 & 1 & 0 & 0 & 0 & 1 & 1 & 1 & 1 \\ \end{pmatrix}
It works with the MathJax option in preferences. Can you check if there's an error in the page, else it's a bug the (default) PNG renderer which should be reported. 23:39, 4 June 2014 (UTC)

Hadn't seen this because I use MathJax. I just tried to fix it, but it seems the LaTeX backend just can't handle a matrix more with more than ten columns... QVVERTYVS (hm?) 09:04, 5 June 2014 (UTC)
