 1.4 Introduction to version 1.4 of the extension
 
-Version 1.4 adds a couple more capabilities to further expose the

-
-   • Per-crtc pixmaps. This provides for multiple scan-out buffers
-     which applications can create and assign to arbitrary collections
-     of crtcs.
-
-   • Sprite position and image transforms. These provide a projective
-     transform for both the hot spot location and the sprite image
-     itself for each CRTC.
-
-   • RRSetCrtcConfigs request. This supplies a set of
-     crtc configurations to the server that must be applied together
-     or not at all. This can reduce screen flicker while also
-     providing the server a complete configuration for appropriate
-     resource management.

-The first two additions, per-crtc pixmaps and sprite transforms are
-designed to solve two problems:
-
- 1) Screen transforms. The software transform code in the X server
-    uses a shadow frame buffer, adding another copy to every graphics
-    operation. Worse, the server has no idea about when clients are
-    done drawing a frame, so the user gets additional latency and
-    judder.
-
-    The goal is to move this operation out to the compositing manager
-    which already deals with an extra copy of the frame buffer for
-    many operations. Have the compositing manager create and draw to a
-    separate pixmap for scanout. It can perform whatever transforms
-    are required to get the image in the right orientation for the
-    user.
-
- 2) Hardware scanout engine size limits. With a single scanout buffer
-    for the entire screen, it's possible for the user to ask for a
-    configuration which requires that scanout buffer to be larger than
-    the hardware is capable of scanning out from. Again, having the
-    compositing manager create a pixmap for each CRTC will allow for
-    any configuration where monitor position within the virtual space
-    isn't limited by the scanout limits.
-
-In both of these cases, the Sprite transforms are necessary to ensure
-that the sprite appears at the desired spot on each CRTC and with the
-right shape.

-
-SCANOUTPIXMAPINFO { format: PICTFORMAT
-		    maxWidth, maxHeight: CARD16
-		    rotations: SETofROTATION }
-
-	'format' is the format of the pixels within the scanout
-	pixmap. Only 'Direct' formats are supported, this will never
-	be an 'Indexed' format.
-
-	'maxWidth' and 'maxHeight' define the largest supported
-	scanout pixmap. There is no minimum size; scanout pixmaps down
-	to 1x1 may be created.
-
-	'rotations' lists the set of rotations which can be provided
-	without additional latency or memory usage within the
-	environment. This typically means that they are supported
-	directly by the hardware. It is expected that a compositing
-	manager will perform other transforms as a part of the
-	compositing process in conjunction with the sprite transforms
-	described in this extension.

-
-	If 'set' includes SetCrtcSpriteImageTransform, then
-	sprite-image-transform is used as in the
-	RRSetCrtcSpriteTransform request image-transform parameter.
-
-	If 'set' includes SetCrtcPixmap, then 'pixmap' specifies the
-	origin of the pixel data to be presented on 'crtc'. If
-	'pixmap' is None, then data will be presented from the screen
-	pixmap.
-
-	If 'set' includes SetCrtcPixmapPosition, then 'pixmap-x' and
-	'pixmap-y' specify the origin of the scanout data within the

-	If 'set' includes SetCrtcPixmap, then 'pixmap' must specify a

-
-	 * 'pixmap' must be at least as large as the area to be
-	   scanned out, or a Match error results.
-
-	 * If 'pixmap' is destroyed while still being used as a
-	   scanout pixmap, then the associated CRTC will have its
-	   scanout pixmap set back to None, the CRTC origin set back
-	   to 0,0 (to make sure it fits) and the screen pixmap width
-	   and height increased to be at least as big as the current
-	   CRTC mode.
-
-	 * Future crtc changes that do not change the scanout pixmap
-	   will cause an existing scanout pixmap to be resized to be
-	   large enough to hold the new mode at the then-current
-	   pixmap-x/pixmap-y location.
-
-	If 'set' includes SetCrtcRotation then:
-
-	 * Any new or existing scanout pixmap must have had the
-	   specified 'rotation' included as a part of its creation
-	   parameters, or a Match error results.
-
-	 * If no scanout pixmap is in use, then the crtc must support
-	   'rotation' else a Value error results.
