virtual ClipCoverage | GetClipCoverage (const Entity &entity, const std::optional< Rect > ¤t_clip_coverage) const |

overridevirtual |
Whether or not this contents can accept the opacity peephole optimization.
By default all contents return false. Contents are responsible for determining whether or not their own geometries intersect in a way that makes accepting opacity impossible. It is always safe to return false, especially if computing overlap would be computationally expensive.
Reimplemented from impeller::ColorSourceContents.

Get or register shader.
Resolve runtime stage function.
Set up the command. Defer setting up the pipeline until the descriptor set layouts are known from the uniforms.
Fragment stage uniforms.
Now that the descriptor set layouts are known, get the pipeline.
