LibWeb: Add Exposed attribute and IDL spec links where missing The intent is to use these to autogenerate prototype declarations for Window and WorkerGlobalScope classes. And the spec links are just nice to have :^) 2022-10-07 16:45:09 -06:00			`// https://html.spec.whatwg.org/multipage/semantics.html#htmlcanvaselement`

LibWeb: Add a bunch of missing CEReactions This is almost guaranteed not to be all CEReactions we need to add, but this puts us in a much better situation. 2023-03-01 01:45:18 +00:00			`[CEReactions] attribute unsigned long width;`

LibWeb: Fix Canvas.toDataURL and Canvas.toBlob signatures Fix the function signatures of Canvas.toDataURL() and Canvas.toBlob() and make both functions accept non-numbers as the quality parameter, in which case it will just use the default quality instead of raising an exception. This makes toDataURL.arguments.1.html, toDataURL.arguments.2.html and toDataURL.jpeg.quality.notnumber.html in wpt/html/semantics/embedded-content/the-canvas-element pass :^) 2024-11-08 09:13:54 +01:00			`USVString toDataURL(optional DOMString type = "image/png", optional any quality);`
