>the rendering engine is built into the system as the underlying graphics toolkit. As far as I know Windows RT supports developing apps in Javascript/CSS so it sounds like Trident is pretty built in to Windows RT. That has not stopped Mozilla calling for the ability to bring Firefox to Windows RT [1]. >(Presumably there is nothing stopping someone implementing a browser in a HTML5 canvas, and Mozilla certainly wouldn't "ban" such an app.) There is nothing stopping Mozilla doing that for iOS but they (rightly) want to be able to release a browser that has decent performance.
