The CanvasGradient interface represents an opaque object describing
gradient. It is returned by the methods `CanvasRenderingContext2D.createLinearGradient()`
`CanvasRenderingContext2D.createRadialGradient()`.

The CanvasPattern interface represents an opaque object describing
pattern, based on an image, a canvas, or a video, created by
`CanvasRenderingContext2D.createPattern()` method.

The CanvasRenderingContext2D interface, part of the Canvas API,
the 2D rendering context for the drawing surface of a `<canvas>`
It is used for drawing shapes, text, images, and other objects.

web.canvas interfaces.

The HTMLCanvasElement interface provides properties and methods
manipulating the layout and presentation of `<canvas>` elements.
HTMLCanvasElement interface also inherits the properties and
of the `web.dom.HTMLElement` interface.

HTMLCanvasElement Events.

The ImageBitmap interface represents a bitmap image which can
drawn to a `<canvas>` without undue latency. It can be created
a variety of source objects using the `createImageBitmap()` factory
ImageBitmap provides an asynchronous and resource efficient pathway
prepare textures for rendering in WebGL.

The ImageBitmapRenderingContext interface is a canvas rendering
that provides the functionality to replace the canvas's contents
the given `web.canvas.ImageBitmap`. Its context id (the first
to `HTMLCanvasElement.getContext()` or `OffscreenCanvas.getContext()`)
\"bitmaprenderer\".

The ImageData interface represents the underlying pixel data
an area of a `<canvas>` element. It is created using the `ImageData()`
or creator methods on the `web.canvas.CanvasRenderingContext2D`
associated with a canvas: `createImageData()` and `getImageData()`.
can also be used to set a part of the canvas by using `putImageData()`.

The OffscreenCanvas interface provides a canvas that can be rendered
screen. It is available in both the window and worker contexts.

The Path2D interface of the Canvas 2D API is used to declare
path that can then be used on a `web.canvas.CanvasRenderingContext2D`
The path methods of the CanvasRenderingContext2D interface are
present on this interface, which gives you the convenience of
able to retain and replay your path whenever desired.

The TextMetrics interface represents the dimensions of a piece
text in the canvas, as created by the `CanvasRenderingContext2D.measureText()`
