[GPU] Add FXAA post-processing [UI] Add FidelityFX FSR and CAS post-processing [UI] Add blue noise dithering from 10bpc to 8bpc [GPU] Apply the DC PWL gamma ramp closer to the spec, supporting fully white color [UI] Allow the GPU CP thread to present on the host directly, bypassing the UI thread OS paint event [UI] Allow variable refresh rate (or tearing) [UI] Present the newest frame (restart) on DXGI [UI] Replace GraphicsContext with a far more advanced Presenter with more coherent surface connection and UI overlay state management [UI] Connect presentation to windows via the Surface class, not native window handles [Vulkan] Switch to simpler Vulkan setup with no instance/device separation due to interdependencies and to pass fewer objects around [Vulkan] Lower the minimum required Vulkan version to 1.0 [UI/GPU] Various cleanup, mainly ComPtr usage [UI] Support per-monitor DPI awareness v2 on Windows [UI] DPI-scale Dear ImGui [UI] Replace the remaining non-detachable window delegates with unified window event and input listeners [UI] Allow listeners to safely destroy or close the window, and to register/unregister listeners without use-after-free and the ABA problem [UI] Explicit Z ordering of input listeners and UI overlays, top-down for input, bottom-up for drawing [UI] Add explicit window lifecycle phases [UI] Replace Window virtual functions with explicit desired state, its application, actual state, its feedback [UI] GTK: Apply the initial size to the drawing area [UI] Limit internal UI frame rate to that of the monitor [UI] Hide the cursor using a timer instead of polling due to no repeated UI thread paints with GPU CP thread presentation, and only within the window
