RAII bracket for QRhi::beginOffscreenFrame / endOffscreenFrame. More...

Detailed Description

RAII bracket for QRhi::beginOffscreenFrame / endOffscreenFrame.

A frame that is begun is always ended, including when the scope is left by an exception: QRhi keeps inFrame set otherwise and every later beginFrame / beginOffscreenFrame on that QRhi silently does nothing for the rest of the session.

beginOffscreenFrame returns FrameOpSuccess without writing the command buffer when a frame is already recording (qrhi.cpp only warns and returns early), so success alone does not mean a frame was opened here. In that case the scope owns nothing and must not end the frame that is already running.
