Rendering of TeX equations in documentation

[dhardy]

Some boost documentation uses TeX formulae, e.g. for the PDFs of distributions. Unfortunately these equations are rendered at a fixed low resolution, making the terms in some of them quite difficult to read (especially where the equations appear inline and contain things like \e ^ \frac ...). Examples (under "Description"):

https://www.boost.org/doc/libs/1_69_0/doc/html/boost/random/lognormal_distribution.html
https://www.boost.org/doc/libs/1_69_0/doc/html/boost/random/poisson_distribution.html

Please at least increase the rendering size. Other options might be to move these equations out-of-line (thus increasing size) or using mathjax.
