Rendering pipeline

selected document entries -> QShader package -> RenderPass
    -> QRhi bindings/pipeline -> command recording -> presentation

Render Toy records Scene into an offscreen texture and Post samples it. ShaderToy records one fullscreen consumer. Resources referenced by prior frames are retired for at least maxFrameLatency + 1 frames rather than freed synchronously.

Implementation

Relevant source: rendering/SlangRhiWidget.cpp, RenderPass.cpp, and Qt68ShaderBridge.cpp.
