63d3229: VR renders LaTex (python 2 only)

[Edward K. Ream]

It renders LaTeX using mathjax in a QtWebKitWidgets.QWebView.

This is experimental code, and only works with Python 2. On my Windows 10 machine, it hangs when using Python 3. I have no idea why.

Even on a fast machine, it takes several seconds to render Maxwell's equations:

\begin{align}
  \nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} & = \frac{4\pi}{c}\vec{\mathbf{j}} \\
  \nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \\
  \nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \\
  \nabla \cdot \vec{\mathbf{B}} & = 0
\end{align}
yielding the attached image. I'll be testing on Ubuntu next.

I should have added that VR plugin avoids the hang by not rendering when g.isPython3 is True. Not great, but better than hanging ;-)

On Linux, rendering is much faster than on Windows and works for both Python 2 and 3.

Rev 20601c disables rendering only on Windows and only when using Python 3.
