Translations:Texvc PHP Alternative/3/en

Mediawiki uses an additional program, Texvc, to render math into nice images for page display. Unfortunately texvc needs to be compiled and is written in OCaml which can pose a problem on most public hosts even if all the other requirements are met (ghostscript, latex, etc). This work around replaces the Math rendering code with an in suite PHP version, performing all the image manipulations, renderings, etc that Texvc would normally do.
