 <pre>//Render Activities define the execution language of the render engine.//
 The [[Scheduler]] maintains the ability to perform these Activities, in a time-bound fashion, observing dependency relations; activities allow for notification of completed work, tracking of dependencies, timing measurements, re-scheduling of other activities -- and last but not least the dispatch of actual [[render jobs|RenderJob]]. Activities are what is actually enqueued with priority in the scheduler implementation, they are planned for a »µ-tick slot«, activated once when the activation time is reached, and then forgotten. Each Activity is a //verb//, but can be inhibited by conditions and carry operation object data. Formally, activating an Activity equates to a predication, and the subject of that utterance is »the render process«.
