Subject: [PATCH] Added new `layerIds` option to layerControl configuration.
 This array determines which sublayer and folder controls are visible. The
 visibility of the actual sublayers is not affected.

Also includes `layerIds` array in imageParameters to demonstrate how to
set the initial visibility of sublayers.
