In bug 940842 I started investigating adding a new CSS property 'will-animate' to let authors give better descriptions of their intents instead of relying on our complicated, and unpredictable, internal heuristics. The better the platform can understand what the page is trying to do, the better it can optimize. This has the results that the page behave more like a native app would from the perspective of the hardware and GPU. I'm glossing over a lot of details here. If you want more information or would like to comment on that proposal please see bug 940842 and the www-style discussion[1].
For those interested this proposal is going to be a contributing factor to 'performance polish' and battery. Namely when our average FPS is near 55-60, we can drop 5 sequential frames briefly preparing an animation. I'd like some feedback on enabling this CSS property for B2G only. I plan on landing this property behind a preference but setting this preference for B2G by default so that gaia can use it. Once the spec is accepted I will enable this everywhere [1] http://lists.w3.org/Archives/Public/www-style/2013Nov/0414.html _______________________________________________ dev-b2g mailing list dev-b2g@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-b2g
