+Subject: [PATCH] [XProto] Fix underflow in Fp1616ToDouble
+
+x11::Input::Fp1616 should be treated as a signed integer, otherwise
+-1 will underflow to 65535.  When dragging a scrollbar, this would
+cause the scrollbar to snap to the bottom when the cursor is dragged
+above the window's y=0 coordinate.  Verified that the issue is fixed
+after this CL.
