522389 - Implement some sort of cached rendering to offscreen textures

Status: RESOLVED WORKSFORME

(Core :: SVG, defect)

Description

[Jonathan Watt [:jwatt]]

Given our eminent support of SMIL and CSS Transitions, we should implement some sort of caching of rendering to offscreen textures. SVG Tiny 1.2 introduced a property called 'buffered-rendering', but I'm not convinced it's a great solution.

Opera apparently now implements it though, and Ed demoed it at SVG Open 2009.

Layers has provided what we need. There are certainly cases where we can and should leverage Layers more effectively for SVG, but we should do that on a case-by-case bases in individual perf bugs as we encounter them.
