• Request configuration from driver, either 1.0 or 1.2 style

->rrGetInfo
1.0:

RROutputSetCrtc
RRModeGet

• Must delay scanning configuration until after ->rrGetInfo returns

of the ->rrGetInfo operation.
1.0:
• Scan old configuration, mirror to new structures
RRScanOldConfig
RRCrtcCreate
RROutputCreate
RROutputSetCrtcs
RROutputSetCrtc
RROutputSetConnection
RROutputSetSubpixelOrder
RROldModeAdd • This adds modes one-at-a-time
RRModeGet
RRCrtcNotify
• send events, reset pointer if necessary
RRTellChanged
WalkTree (sending events)
• when layout has changed:
RRPointerScreenConfigured
RRSendConfigNotify
Asynchronous state setting (1.2 only)
When setting state asynchronously, the driver invokes the
->rrGetInfo function and then calls RRTellChanged to flush
the changes to the clients and reset pointer if necessary
