ximagesrc: Fix the destination coordinates of the cursor

Browse source 
XFixes provides the cursor coordinates relative to the root window, this
is not taken into account when using the xid property to capture
a specific window, the result is that the cursor gets drawn at the wrong
position.

In order to fix this consider the window location when calculating the
cursor position in the destination image.
