+Specifies the 3x3 transformation matrix for absolute input devices. The
+input device will be bound to the area given in the matrix.  In most
+configurations, "a" and "e" specify the width and height of the area the
+device is bound to, and "c" and "f" specify the x and y offset of the area.
+The value range is 0 to 1, where 1 represents the width or height of all
+root windows together, 0.5 represents half the area, etc. The values
+represent a 3x3 matrix, with the first, second and third group of three
+values representing the first, second and third row of the matrix,
+respectively.  The identity matrix is "1 0 0 0 1 0 0 0 1".
 .SS POINTER ACCELERATION
 For pointing devices, the following options control how the pointer
 is accelerated or decelerated with respect to physical device motion. Most of
