for compensating for the overscan behavior of certain

+Version 1.4 adds a new object called a provider object. A provider object
+represents a GPU or virtual device providing services to the X server.
+Providers have a set of abilities and a set of possible roles.
+
+Provider objects are used to control multi-GPU systems. Provider roles can
+be dynamically configured to provide support for:
+
+ 1) Output slaving: plug in a USB device, but have its output rendered
+ using the main GPU. On some dual-GPU laptops, the second GPU isn't
+ connected to the LVDS panel, so we need to use the first GPU as an output
+ slave for the second GPU.
+
+ 2) offload - For dual-GPU laptops, allow direct rendered applications to be run
+ on the second GPU and display on the first GPU.
+
+ 3) GPU switching - Allow switching between two GPUs as the main screen
+ renderer.
+
+ 4) multiple GPU rendering - This replaces Xinerama.

+ provider. If the property is marked as a 'pending' property, only the
+ pending value of the property is changed. Otherwise, changes are
+ reflected in both the pending and current values of the property.
+ The type is uninterpreted by the server. The format specifies

+ 32-bit quantities so that the server can correctly byte-swap as
+ necessary.
+
+ If the mode is Replace, the previous property value is discarded.
+ If the mode is Prepend or Append, then the type and format must

+ is L. However, it is a Value error if long-offset is given such
+ that L is negative. The value of bytes-after is A, giving the
