 1.3 Introduction to version 1.3 of the extension
 
 Version 1.3 builds on the changes made with version 1.2 and adds some new
-capabilities without fundmentally changing the extension again. This version
-adds 'panning regions' and projective transforms, plus defines some standard
-output properties to help clients describe the systme more accurately.

+capabilities without fundmentally changing the extension again. The
+following features are added in this version:
+
+   • Projective Transforms. The implementation work for general rotation
+     support made it trivial to add full projective transformations. These
+     can be used to scale the screen up/down as well as perform projector
+     keystone correct or other effects.
