This is not correct, it only counts for MouseUp and Down

Wasn't OK. It uses gtk_grab, this one also grabs the keyboard. The windows 
capture only captures the mouse. I changed it to gdk_grab.

After some investigations where the CM_MouseEnter and CM_MouseLeave are 
generated, they appeared in the Application.Idle loop.
I started implementing this through gtk_idle_add and a OnIdle event 
property of the InterfaceBase, but didn't finish
