Base class for 3D texture types. Base class for [Texture2DArray], [Cubemap] and [CubemapArray]. Cannot be used directly, but contains all the functions necessary for accessing the derived resource types. Data is set on a per-layer basis. For [Texture2DArray]s, the layer specifies the array layer. Returns the current format being used by this texture. See [enum Image.Format] for details. Returns the height of the texture. Height is typically represented by the Y-axis. Returns an [Image] resource with the data from specified [code]layer[/code]. Returns the width of the texture. Width is typically represented by the X-axis.
