When using the Edit > Paste menu, or when pressing Ctrl+V while the Graph Editor has the focus but the mouse is not contained in it, there is no current mouse position in the GraphEditor so the position that is provided to the "pasteNodes" function is the last known mouse position, which is oftentimes on the border of the GraphEditor. This commit automatically sets the mouse's position to the center of the GraphEditor, and "builds" the zone containing the pasted nodes around it.
