    Since I would like to get information about what direction to extend the
    drawings, the situation complicates if I have a sequence of RESIZE, MOVE,
    RESIZE.

  I don't understand.  Your decision should be independent of what gestures
  the user might have made to resize the window.

Unless a "photo cropping" type of user interface is desired. The user
drags an edge (or corner) to uncover or obscure the adjacent part of the
drawing. Using a BitGravity and WindowGravity of StaticGravity in a
subwindow which is larger than its parent window (which may be
considered a viewport onto the subwindow) may accomplish what you want.
