Examples `HTMLImageElement`, - * `HTMLCanvasElement`, `HTMLVideoElement`. - * - * If `number[]` or `ArrayBuffer` it's assumed to be data for a texture. If `width` or `height` is - * not specified it is guessed as follows. First the number of elements is computed by `src.length / numComponets` - * where `numComponents` is derived from `format`. If `target` is `gl.TEXTURE_CUBE_MAP` then `numElements` is divided - * by 6. Then - * - * * If neither `width` nor `height` are specified and `sqrt(numElements)` is an integer then width and height - * are set to `sqrt(numElements)`. Otherwise `width = numElements` and `height = 1`. - * - * * If only one of `width` or `height` is specified then the other equals `numElements / specifiedDimension`. - * - * If `number[]` will be converted to `type`. - * - * If `src` is a function it will be called with a `WebGLRenderingContext` and these options. - * Whatever it returns is subject to these rules. So it can return a string url, an `HTMLElement` - * an array etc... - * - * If `src` is undefined then an empty texture will be created of size `width` by `height`. - * - * @property {string} [crossOrigin] What to set the crossOrigin property of images when they are downloaded. - * default: undefined.
