 * Base class for PathAtlas implementations that rasterize coverage masks on the GPU using compute
 * shaders.
 *
 * When a new shape gets added, it gets tracked as input to a series of GPU compute passes. This
 * data is recorded by `recordDispatches()` into a DispatchGroup which can be added to a
 * ComputeTask.
 *
 * After a successful call to `recordDispatches()`, the client is free to call `reset()` and start
 * adding new shapes for a future atlas render.
