it a little less mysterious.

 * @num_crtcs: CRTC count

 * @num_encoders: encoder count

 * @num_connectors: connector count

 * @id_list: list of KMS object IDs in this group

 *

 * Currently this simply tracks the global mode setting state.  But in the

 * future it could allow groups of objects to be set aside into independent

 * control groups for use by different user level processes (e.g. two X servers

 * running simultaneously on different heads, each with their own mode

 * configuration and freedom of mode setting).
