 * PathAtlas class that rasterizes coverage masks on the CPU.
 *
 * When a new shape gets added, its path is rasterized in preparation for upload. These
 * uploads are recorded by `recordUploads()` and subsequently added to an UploadTask.
 *
 * Shapes are cached for future frames to avoid the cost of raster pipeline rendering. Multiple
 * textures (or Pages) are used to cache masks, so if the atlas is full we can reset a Page and
 * start adding new shapes for a future atlas render.
