*
* @param tuc cache of unused tiles or @c NULL to create one
* automatically.
* @param cols number of columns in the matrix.
* @param rows number of rows in the matrix.
* @param cspace the color space used to create tiles in this matrix.
* @param render_cb function used to render given tile update.
* @param data context to give back to @a render_cb.
*
* @return newly allocated instance on success, @c NULL on failure.
