Detailed Description

A task for rendering geometry to pixels.

Rendering state management can be handled two ways: 1.) An application can create an HdxRenderTask and pass it the HdxRenderTaskParams struct as "params". 2.) An application can create an HdxRenderSetupTask and an HdxRenderTask, and pass params to the setup task. In this case the setup task must run first.

Parameter unpacking is handled by HdxRenderSetupTask; in case #1, HdxRenderTask creates a dummy setup task internally to manage the sync process.

Case #2 introduces complexity; the benefit is that by changing which setup task you run before the render task, you can change the render parameters without incurring a hydra sync or rebuilding any resources.
