bindPipeline method
Binds the pair of stages the following draws run.
Bindings do not survive this call. A backend is free to drop every buffer, uniform and texture binding when the pipeline changes — the flutter_gpu backend must, because its pass replays every binding it has ever been handed at each draw, keyed by the shader that bound it, and a stale block from the previous pipeline's shader can land on a slot the new pipeline reads. Every site in this engine therefore binds what a draw needs after binding its pipeline, never before.
Implementation
@override
void bindPipeline(PipelineHandle pipeline) =>
commands.add(RecordedPipeline(pipeline));
