Accelerated 2D and 3D Graphics in Qt 6
summary
Qt 6 replaces direct GL-only rendering with a new QRhi rendering hardware interface and a build-time shader pipeline using glslang + spirv-cross to produce qsb shader bundles that work as Vulkan/Metal/Direct3D or GL at runtime. Qt Quick and Qt 3D render 2D and 3D in a unified scene graph single render path (reducing texture-blit composition), QQuickRenderControl lets Quick render into Vulkan/Metal/D3D images (including OpenXR render targets), examples run unchanged on D3D or GL, and ANGLE is no longer shipped.
