 * `dpi` (Integer, default: 300). Used in calculations when units are used (e.g. for PDF rendering and unit conversion).
 * `hint` (ColorString, default: off). Text hints are used to show the boundaries of text boxes. Can be enabled/disabled for individual commands, or set globally with the `set` command. This setting is overriden by `set` and individual commands.
 * `custom_colors` (Hash of Colors, default: {}). Defines globally-available colors available to the deck that can be specified in commands.
-* `antialias` (`fast, good, best, none`, default: best). Set the algorithm that Cairo will use for antialiasing. Using our benchmarks on large decks, `best` is only X% slower anyway. For more info see the [Cairo docs](http://www.cairographics.org/manual/cairo-cairo-t.html#cairo-antialias-t).

 * `backend` (`svg` or `memory`, default: `memory`). Defines how Cairo will store the operations. Memory is recommended for higher quality rendering.
 * `prefix` (default: `card_`). When using an SVG backend, cards are auto-saved with this prefix and `"%02d"` numbering format.
