- OpenGLRenderer: hold the viewer-owned QOpenGLContext in a QPointer so DestroyInternal() safely skips it when the context has already been destroyed by Qt's shared-context lifecycle. Fixes a SIGSEGV when the full gtest suite ran MainWindow.ConstructsOffscreenWithPanelsAndMenus after earlier viewer tests. - PreviewAudioDevice: add SetParams() deriving bytes_per_frame from the audio format (bytes per sample * channel count) instead of staying 0.
