The fFinishedProc is called when the Recording has been submitted and finished on the GPU, or when there is a failure that caused it not to be submitted. The callback will always be called and the caller can use the callback to know it is safe to free any resources associated with the Recording that they may be holding onto. If the Recording is successfully submitted to the GPU the callback will be called with CallbackResult::kSuccess once the GPU has finished. All other cases where some failure occured it will be called with CallbackResult::kFailed.
The fTargetSurface, if provided, is used as a target for any draws recorded onto a deferred canvas returned from Recorder::makeDeferredCanvas. This target surface must be provided iff the Recording contains any such draws. It must be Graphite-backed and its backing texture's TextureInfo must match the info provided to the Recorder when making the deferred canvas.
fTargetTranslation is an additional translation applied to draws targeting fTargetSurface.
The client may pass in two arrays of initialized BackendSemaphores to be included in the command stream. At some time before issuing commands in the Recording, the fWaitSemaphores will be waited on by the gpu. We only guarantee these wait semaphores block transfer and fragment shader work. Similarly, at some time after issuing the Recording's commands, the fSignalSemaphores will be signaled by the gpu. Depending on the platform, the timing of the wait and signal operations will either be immediately before or after the given Recording's command stream, respectively, or before and after the entire CommandBuffer's command stream. The semaphores are not sent to the GPU until the next Context::submit call is made.
The client will own and be responsible for deleting the underlying semaphore objects after the submission completes, however the BackendSemaphore objects themselves can be deleted as soon as this function returns.
