/**
 * cogl_texture_2d_gl_new_from_foreign:
 * @ctx: A #CoglContext
 * @gl_handle: A GL handle for a GL_TEXTURE_2D texture object
 * @width: Width of the foreign GL texture
 * @height: Height of the foreign GL texture
 * @format: The format of the texture
 *
 * Wraps an existing GL_TEXTURE_2D texture object as a #CoglTexture2D.
 * This can be used for integrating Cogl with software using OpenGL
 * directly.
 *
 * The texture is still configurable until it has been allocated so
 * for example you can declare whether the texture is premultiplied
 * with cogl_texture_set_premultiplied().
 *
 * <note>The results are undefined for passing an invalid @gl_handle
 * or if @width or @height don't have the correct texture
 * geometry.</note>
 *
 * Returns: (transfer full): A newly allocated #CoglTexture2D
 *
 * Since: 2.0
