 One year ago today, I was finishing the first implementation of [block layout](https://github.com/twilco/kosmonaut/commit/f3041f0b7e986b7a0be26b34870489cfaeb3e830) and [display-list generation](https://github.com/twilco/kosmonaut/commit/fedf68029e4ad9ea8bf4b96611b8738a347402f2).  In terms of LoC, Kosmonaut hasn't grown much — from 7.5k LoC then to
 20k now.  However, there are some pretty neat improvements wrapped up in that 12.5k LoC increase:
 
-* Layout-tree dump{% fn %} snapshot based testing
-* Partial support{% fn %} for [abstract box layout](https://drafts.csswg.org/css-writing-modes-4/#abstract-layout) with the `writing-mode` and `direction` properties

 * Support for arbitrary scale factors, e.g. for HiDPI screens
 * OpenGL-based box painting and text rendering (though text rendering is not yet hooked into layout)
