The Waveform, Vectorscope and Histogram panels were black when running on the Vulkan / backend-neutral render path because ScopeBase::OnPaint() returned early with a TODO. The viewer emits GPU textures that live in the viewer's own renderer; on Vulkan each ManagedDisplayWidget has a separate device, so those textures cannot be sampled directly. Fix by: - Adding a backend-neutral branch in ScopeBase::OnPaint() that downloads the reference texture (cross-renderer if needed), color-manages it into a U8 offscreen texture, downloads it to a QImage, and draws via QPainter. - Adding a pure virtual DrawScopeSoftware() to ScopeBase and implementing it for WaveformScope, VectorscopeScope and HistogramScope. - Fixing the managed_tex_up_to_date_ flag that was never set to true in the OpenGL path, which caused the color-managed scope texture to be recreated on every paint. All gtest suites pass.
