/**
 * PathAtlas manages one or more atlas textures that store coverage masks for path rendering.
 *
 * The contents of a PathAtlas are intended to be transient: atlas regions are considered valid only
 * for the scope of the render passes that sample them. Unlike DrawAtlas, PathAtlas does not
 * necessarily support partial eviction and reuse of subregions. In most subclasses, once an atlas
 * texture is filled up all of its sub-allocations must be invalidated before it can be reused.
 *
 * PathAtlas does not prescribe how atlas contents get uploaded to the GPU. The specific task
 * mechanism is defined by subclasses.
