[lazarus] Bugfixes

[Shane Miller]

I have (sort of) fixed the bug that causes the wrong mouse coordinates to be reported for the mouse move event.  I have corrected it in gtkobject so I have removed the work around in Designer.pp.

The fix compares the gdwindow of the event to the parent's gdkwindow.  If they are the same then it changes the x and y coord's to report them relative to the control instead of the parent control.
