/** @param c contains the current Display 'channels' value (the transparencies of each channel). This method creates a new color image in which each channel (R, G, B) has the corresponding alpha (in fact, opacity) specified in the 'c'. This alpha is independent of the alpha of the whole Patch. The method updates the Loader cache with the newly created image. The argument 'imp' is optional: if null, it will be retrieved from the loader.
 * <p>
 * For non-color images, a standard image is returned regardless of the given {@code c}.
