Added ImageBitmap interface

[nkemnitz]

Fixes ImageBitmap interface missing #14402

Adds interfaces ImageBitmap, ImageBitmapOptions and the associated typedefs to Window and Worker scope. See WHATWG HTML Living Standard

Wasn't sure about the "flavor" tag. Worker seems to be the one I need here. but is there a description of All, Web, DOM and maybe others?

this should be "Web", DOM interfaces are not available in Web Workers.

We will need two entries for createImageBitMap, or at least two definitions for ImageBitmapSource, one for WebWorkers that does not have HTMLImageElement, SVGElement, HTMLVideoElement, or HTMLCanvasElement

consolodate all the types in one type def. we try to avoid polluting the global namespace.

type ImageBitmapSource = HTMLImageElement | SVGImageElement | HTMLVideoElement | HTMLCanvasElement | ImageBitmap; | Blob | ImageData;

Thanks for the explanation!
I removed the typedefs for both, ImageBitmap and ImageBitmapOptions, as well as the unavailable HTMLElements in the Web Worker createImageBitmap call.

The failing Travis CI build seems not related to the code changes.
