This adds a new dependency on peniko, reintroduces kurbo for geometry (!), removes the now defunct types from piet-scene and updates all the test scenes to use the new types.
Removes the dependency on the piet crate and replaces all uses with the scene crate. Also does some cleanup of the scene API, renaming some types and moving them all to the crate root for better ergonomics.
This removes the GPU transform stage, changes shaders to reference transforms directly from the scene, and modifies the render context to maintain a transform stack.
Adds kurbo as an optional dependency and implements conversions to/from the common types.
This also removes the direct pinot dependency and changes moscato (temporarily) to a git based dep to allow iteration on the underlying glyph loading code without PR churn here.
Adds a test to visualize the blend modes. Fixes a dumb bug in blend.h and also a more subtle issue where default blending is not the same as clipping, as the former needs to always push a blend group (to cause isolation) and the latter does not. This might be something we need to get back to.
This should fix the rendering, so it fairly closely resembles the Mozilla reference image. There's also a compile-time switch to disable sRGB conversion, which is (sadly) needed for compatible rendering.
* Change pgpu-render header file generator to add a comment noting that the file is auto-generated
* Remove bin target and associated dependencies from piet-scene crate
* Remove FP constructors from the Color type
* Better codegen and rounding in Color::to_premul_u32()
* Add kurbo attribution for piet_scene::geometry module
This commit implements actual rendering for the new piet-scene crate.
In particular, it adds a new EncodedSceneRef type in piet_gpu::encoder to store references to the raw stream data. This is used as a proxy for both PietGpuRenderContext and piet_scene::scene::Scene to feed data into the renderer.
Much of this is still hacky for expedience and because the intention is to be a transitional state that maintains both interfaces until we can move to the new scene API and add a wrapper for the traditional piet API.
The general structure and relationships between these crates need further discussion.
