Is it possible to have a texture array of compressed textures?

DataTexture2DArray and DataTexture3D do not support compressed textures.

There is WebGL2RenderingContext.compressedTexImage3D() however I’ve never worked with it so far. So I can’t tell how well it is supported in browsers.

In any event, compressedTexImage3D() is not used by three.js. Only texImage3D().

		} else if ( texture.isDataTexture2DArray ) {

			state.texImage3D( _gl.TEXTURE_2D_ARRAY, 0, glInternalFormat, image.width, image.height, image.depth, 0, glFormat, glType, image.data );
			textureProperties.__maxMipLevel = 0;

		} else if ( texture.isDataTexture3D ) {

			state.texImage3D( _gl.TEXTURE_3D, 0, glInternalFormat, image.width, image.height, image.depth, 0, glFormat, glType, image.data );
			textureProperties.__maxMipLevel = 0;
