Handling of PhotoYCC (YCC), PhotoYCCA (YCCA), RGBA and YCbCrA color spaces
by the standard plugin, as described below, is dependent on capabilities
of the libraries used to interpret the JPEG data. Thus all consequential
behaviors are optional. If the support is not available when decoding,
the color space will be treated as unrecognized and the appropriate

may be used.
When writing, an Exception may be thrown if no suitable conversion
can be applied before encoding.
But where the support for these color spaces is available, the behavior
must be as documented.
