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 :^) 2022-10-08 01:45:09 +03:00			`// https://html.spec.whatwg.org/multipage/semantics.html#htmlcanvaselement`
LibWeb: Port HTMLCanvasElement interface from DeprecatedString to String 2023-09-03 06:58:55 +03:00			`[Exposed=Window]`

LibWeb: Add missing constructors to HTMLElement IDLs 2023-03-23 10:48:52 +03:00			`[HTMLConstructor] constructor();`

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 04:45:18 +03:00			`[CEReactions] attribute unsigned long width;`

LibWeb: Add basic support for HTMLCanvasElement.toDataURL() :^) This allows you to serialize a <canvas> element's bitmap into a data: URI. Pretty neat! :^) 2021-04-20 00:47:29 +03:00			`USVString toDataURL(optional DOMString type = "image/png", optional double quality);`
