[Impeller] Implement the FragmentProgram API. #102853
Description
- Don't hardcode ink sparkle SPIR-V #102674
- When Impeller is enabled with the tool flag
--enable-impeller, theimpellercinvocation should pass the correct backend-specific flags - When Impeller is enabled in the Engine, the Engine should assume that byte buffers passed to the FragmentProgram API are shaders that are appropriate for the current backend rather than spir-v bytecode that has to be transpiled.
- [Impeller] Devise a format for data that will be used by the FragmentProgram API. #104750
- [Impeller] Make SPIRV ingestable by ImpellerC. #104776
- [Impeller] Enable RuntimeStage tests for the OpenGL ES backend. #105538
- [Impeller] Remove allocation + copy of uniforms for RuntimeEffectContents #113714
- [Impeller] Add support for non-struct uniform names for GLES #113715
- [Impeller] RuntimeEffect: Register the shader function earlier #113719
- Replace the
DlImageSamplingenum with finer grainedDlSamplingOptionsstruct #115794
