This change makes Windows render tabs as a single space. Previously, tabs rendered differently depending on your platform:
* Windows, Web - a tofu is rendered
* iOS, Android, macOS, Linux - a single space is rendered
Part of flutter/flutter#79153
* Implement toGpuImage, a synchronous, GPU-resident version of
Picture.toImage.
This method kicks off asynchronous work on the raster task runner.
If it fails to rasterize, it will synchronously throw later when
the user attempts to draw to a canvas.
This supports several use cases:
- Quickly snapping off an expensive-to-rasterize image for reuse
across multiple frames.
- Applying multi-pass filters to a render target.
This patch amends flutter_tester so that it can produce an image
object, but that image will always be a grey and white four square checkerboard.
Adds support for CanvasKit on Web, which basically already used
this method for its Picture.toImage implementation.
Throws an UnsupportedError for HTML on Web, since any implementation
there would almost certainly be slower than drawPicture.
Roll Swiftshader, ANGLE, and Vulkan deps.
Updates license bot for new locations of licenses and new files
in roll.
Converts unit test harnesses to use SwANGLE, which is the
supported way of using SwiftShader as a software backend for GLES.
Updates goldens due to swiftshader changes.
Fixes up include paths to avoid directly including third_party
code by that name, which is unlikely to work in other build
environments.
Includes upstream patches to ANGLE and SwiftShader to build in our
windows environments, as well as patches to Skia to support
defining the location of VulkanMemoryAllocator and a patch to ANGLE
to support opting into a newer version of VMA.
Towards implementing the FragmentProgram API in Impeller.
Specifies an Impeller specific format for data the renderer can use to create
pipelines with user supplied shader stages at runtime.
The data is in the form of a flatbuffer with a known schema.
This patch implements the wire format, creating and loading the program
payloads, and creating pipeline state objects using these payloads.
If the user supplied SPIRV intended for the older API, the loader will reject
this invalid payload. This is probably not going to be too much of an issue
because the FragmentProgram API will probably be modified to only allow buffers
loaded from asset managers. But still, in the meantime, I am using the old API
to pass these new buffers.
