- 

-	    • Request configuration from driver, either 1.0 or 1.2 style

-	    • These functions only record state changes, all

-	      other actions are pended until RRTellChanged is called

- 

-	    ->rrGetInfo

-	    1.0:

-		RRRegisterSize

-		RRRegisterRate

-		RROutputSetCrtcs

-		RRModeGet

-		RROutputSetModes

-		RROutputSetConnection

-		RROutputSetSubpixelOrder

-		RROutputSetClones

-		RRCrtcNotify

- 

-	• Must delay scanning configuration until after ->rrGetInfo returns

-	  because some drivers will call SetCurrentConfig in the middle

-	  of the ->rrGetInfo operation.

- 

-	1.0:

-

-	    • Scan old configuration, mirror to new structures

- 

-	    RRScanOldConfig

-		RRCrtcCreate

-		RROutputCreate

-		RROutputSetCrtcs

-	• 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

-

-Set state

-

-    ProcRRSetScreenConfig

-	RRCrtcSet
