Most of this is (obviously) not necessary to do, but once I started, I figured I'd just get it all. Tools (nanobench, DM, skiaserve), all GMs, benches, and unit tests, plus support code (command line parsing and config stuff). This is almost entirely mechanical.

* Pow2 Rectanizer

|
* Skyline Rectanizer

|
|
* random rects (e.g., pull-save-layers forward use case)
|
|
* random power of two rects
|

* small constant sized power of 2 rects (e.g., glyph cache use case)
