FYI, I've just concocted a POV-Ray grammar file for syntax highlighting
in the Atom text editor and made it publicly available at
https://github.com/c-lipka/language-povray. To my understanding it
should also be possible to import the grammar into TextMate or Sublime Text.

At present the grammar definition is still incomplete, and since I don't
use Atom myself I probably won't be putting much further effort into it
myelf, but any contributions towards extending and refining it would
still be welcome.
