+/**
+ * GrDeferredProxyUploader assists with threaded generation of textures. Currently used by both
+ * software clip masks, and the software path renderer. The calling code typically needs to store
+ * some additional data (T) for use on the worker thread. GrTDeferredProxyUploader allows storing
+ * such data. The common flow is:
+ *
+ * 1) A GrTDeferredProxyUploader is created, with some payload (eg an SkPath to draw).
+ * The uploader is owned by the proxy that it's going to populate.
+ * 2) A task is created with a pointer to the uploader. A worker thread executes that task, using
+ * the payload data to allocate and fill in the fPixels pixmap.
+ * 3) The worker thread calls signalAndFreeData(), which notifies the main thread that the pixmap
+ * is ready, and then deletes the payload data (which is no longer needed).
+ * 4) In parallel to 2-3, on the main thread... Some op is created that refers to the proxy. When
+ * that op is added to an op list, the op list retains a pointer to the "deferred" proxies.
+ * 5) At flush time, the op list ensures that the deferred proxies are instantiated, then calls
+ * scheduleUpload on those proxies, which calls scheduleUpload on the uploader (below).
+ * 6) scheduleUpload defers the upload even further, by adding an ASAPUpload to the flush.
+ * 7) When the ASAP upload happens, we wait to make sure that the pixels are marked ready
+ * (from step #3 on the worker thread). Then we perform the actual upload to the texture.
+ * Finally, we call resetDeferredUploader, which deletes the uploader object, causing fPixels
+ * to be freed.
