1687337 - Caching primitives requires a lot of boilerplate code

Status: NEW

(Core :: Graphics: WebRender, task, P3)

Description

[Nicolas Silva [:nical]]

We have several primitives that do or will use cached render tasks to be rendered via a brush_image shader. The logic to do this has to be duplicated and touches a lot of places in the code.

Ideally we'd have something a bit more generic to render an arbitrary primitive into the cache, render it via a brush image with only a bit of custom code to decide when to trigger this optimization and how to build the cache key.
