Initial implementation of GSK rendering pipeline GSK is conceptually split into two scene graphs: * a simple rendering tree of operations * a complex set of logical layers The latter is built on the former, and adds convenience and high level API for application developers. The lower layer, though, is what gets transformed into the rendering pipeline, as it's simple and thus can be transformed into appropriate rendering commands with minimal state changes. The lower layer is also suitable for reuse from more complex higher layers, like the CSS machinery in GTK, without necessarily port those layers to the GSK high level API. This lower layer is based on GskRenderNode instances, which represent the tree of rendering operations; and a GskRenderer instance, which takes the render nodes and submits them (after potentially reordering and transforming them to a more appropriate representation) to the underlying graphic system.

vulkan: Don't wait until graphics are done computing We can let the GPU do its stuff without waiting. The GPU knows what it's doing. Which means we now get a lot of time to spend on doing CPU things (read: we're way better in benchmarks). The old behavior is safer, so we want to keep it around for debugging. It can be reenabled with GSK_RENDERING_MODE=sync.

gsk: Add GSK_RENDERING_MODE=full-redraw Forces a full redraw every frame. This is done generically, so it's supported on every renderer. For widget-factory first page (with the spinner spinning and progressbar pulsing), I get these numbers per frame: action clipped full redraw snapshot 0ms 7-10ms cairo rendering 0ms 10-15ms Vulkan rendering 3-5ms 18-20ms Vulkan expected * 0ms 1-2ms GL rendering unsupported 55-62ms * expected means disabling rendering of unsupported render nodes, instead of doing fallback drawing. So it overestimates the performance, because borders and box-shadows are disabled.
