| I'm trying to create fonts with a specific pixel height and then render them | |

| Unfortunately, the actual height of the font that's created is always somewhat | |
| larger than the requested height. How do I create a font that has exactly the | |
| right height? |

I'm documenting my experience installing SourceFabric's open source radio station manager Airtime on a clean server Ubuntu 12.04 LTS (Precise Pangolin) server running the popular Virtualmin open-source domain manager.
Virtualmin is sufficiently generic that I imagine the results will be useful to anyone trying to install Airtime on Ubuntu 12.04.
