* compositing: Move image output and shutdown management out of the compositor ↵Martin Robinson2025-02-201-1/+6
| | | | | | | | | | | | | | | | | | | | | | | (#35538) This is a step toward the renderer-per-WebView goal. It moves various details out of `IOCompositor`. - Image output: This is moved to servoshell as now applications can access the image contents of a `WebView` via `RenderingContext::read_to_image`. Most options for this are moved to `ServoShellPreferences` apart from `wait_for_stable_image` as this requires a specific kind of coordination in the `ScriptThread` that is also very expensive. Instead, paint is now simply delayed until a stable image is reached and `WebView::paint()` returns a boolean. Maybe this can be revisited in the future. - Shutdown: Shutdown is now managed by libservo itself. Shutdown state is shared between the compositor and `Servo` instance. In the future, this sharing might be unecessary. - `CompositeTarget` has been removed entirely. This no longer needs to be passed when creating a Servo instance.

* libservo: Expose an `OffscreenRenderingContext` and use it for servoshell ↵Martin Robinson2025-02-171-1/+0
| | | | | | | | | | | | | | | | | | (#35465) Create a new `RenderingContext` which is used to render to a `SurfmanRenderingContext`-related offscreen buffer. This allows having a temporary place to render Servo and then blitting the results to a subsection of the parent `RenderingContext`. The goal with this change is to remove the details of how servoshell renders from the `Compositor` and prepare for the compositor-per-WebView world.

* Move `RenderingContext` to `webrender_traits` (#32386)Martin Robinson2024-05-281-1/+1
| | | | | | The `gfx_traits` crate is gradually become just about text and fonts and this is one of the few things there that is standing in the way of this. Eventually `webrender_traits` will be the general cross-process compositor API, so this sort of makes sense as well.

* gfx: Rename `WebrenderSurfman` to `RenderingContext` and move to `gfx` (#31184)Martin Robinson2024-01-271-2/+2
| | | | | | | | | | | This is a small cleanup that moves and renames this class. The rename is simply because we are exposing a lot about the details of Servo's rendering in the API and it makes sense to start thinking about abstracting that away a bit. This also moves the struct to `gfx`, which does have an effect on Servo's dependency graph. This adds a new dependency on gfx to `compositing`, but `compositing` had a transitive dependency on gfx before through `canvas`.

* Improve decisions in compositor over when to draw a frame.Glenn Watson2017-06-201-1/+0
| | | | | | | | | | | | | | | | | | | | | | This patch fixes a couple of issues in the compositor: 1) Remove the delayed composition code. Previously, this would schedule a composite for 12ms in the future. This doesn't really make any sense with WR. There's no point in doing a composite unless WR has provided a new frame to be drawn. This fixes issues in several benchmarks where we were doing multiple composite / renders per rAF, which is a waste of CPU time. This *does* make the framerate slower in some cases (such as a slow rAF callback) but it's more correct - otherwise we were just compositing the same frame multiple times for no real benefit. 2) Inform the window of the current animation state of the compositor. Specifically, if an animation (or rAF) is currently active, the window system switches to use event polling, and does not block on the OS-level event loop. In the case of active animation, we just assume that we want to be running as the vsync interval and not blocking. This means the compositor thread only sleeps on vsync during animation, which reduces OS scheduling and results in much smoother animation.
