* doc/MaintGeom.3: Noted that Tk_MaintainGeometry handles direct
descendants properly. * generic/tkGeometry.c (Tk_MaintainGeometry): Added a check for the case in which the slave window is a direct descendant of the master window. In this case, we need not set up the additional infrastructure normally provide by Tk_MaintainGeometry, because we can rely on the parent/child relationship to handle it for us implicitly. In this case, Tk_MaintainGeometry just calls directly to Tk_MoveResizeWindow. This allows geometry managers to simply always use Tk_MaintainGeometry to maintain geometry for slaves, and avoid doing the direct descendant check themselves. (Tk_UnmaintainGeometry): Added a matching check for the direct descendant case; in this case, Tk_UnmaintainGeometry simply returns immediately.
