Hi, I've talked with several WebKit engineers here at Apple, including those who invented <canvas>, and the consensus is that adding retained-mode features to the Canvas API is not something we're interested in. The Canvas API is an immediate-mode graphics API. Essentially, it's a programmable <img>. If you want to do hit testing you have to implement it yourself, by tracking what you draw. Grafting random pieces of a retained-mode API into it is bad design. Like folk from Google[1] and Microsoft[2] have pointed out, the Web's retained-mode graphics feature is SVG. > I have a very large IBM application in development and given the state > of SVG accessibility and how the application is constructed it is not > a good fit. If there are accessibility problems with SVG, we should let the SVG WG know about the problems so that they can be fixed. If existing SVG implementations aren't performant enough for your use cases, please file bugs on those implementations.
