+    Rename xf86-mouse.pc to xorg-mouse.pc
+    
+    Other input drivers already shipping pkgconfig files use this naming scheme
+    and since the 1.8 release didn't install the file anyway, renaming is still
+    acceptable at this point.

+
+    Add settable properties for middle mouse button emulation
+    
+    Based on evdev's similar properties, including using the name "middle"
+    button, to avoid confusion with evdev's 3rd button emulation for
+    emulating the right button on a single button mouse.
+    
+    Allows manual enable & disable at runtime.
+    
+    Exports new xf86-mouse.pc & xf86-mouse-properties.h for property name
+    definitions.
