I also dearly would like to have this behavior too.  For pasting there
is of course the mouse-middle button.  And with mouse-yank-at-point it
will paste at the point just like in a raw terminal.

  (setq mouse-yank-at-point t)

But that is only the paste half.  The cut half is still missing.

That is the opposite case.  That covers adding mouse support to a text
terminal.  (Personally I would never want that.  Blech!  But each to
their own.)

The question being asked is to have the graphics terminal behave such
that cutting with the mouse does not move the point.

It is a shame that there isn't some way to create a replacement for
mouse-drag-region that does a save-excursion so that it can cut the
text and then return the point to the previous position when done.  I
have wanted that behavior for years.

In terminal mode everything always works "correctly".  :-)  The desire
would be to have the gui mode work the same.
