CanvasTexture can receive an imageBitmap (used in workers)

[AlexandrosGounis]

A CanvasTexture can also receive an ImageBitmap, and this is how textures are loaded in worker threads.

The supported types should include an ImageBitmap.

This example implements a CanvasTexture using an ImageBitmap:

three.js/examples/js/offscreen/scene.js

Lines 17 to 21 in e9f31ad

	var loader = new THREE.ImageBitmapLoader().setPath( path );
	loader.setOptions( { imageOrientation: 'flipY' } );
	loader.load( 'textures/matcaps/matcap-porcelain-white.jpg', function ( imageBitmap ) {
	var texture = new THREE.CanvasTexture( imageBitmap );
