[gef-dev] Some new features enabled by default in 3.0

[Randy Hudson <hudsonr@xxxxxxxxxx>]

In GEF 3.0 we have added:

constrained resize: hold down SHIFT
and the aspect ratio is constrained during a corner-resize.
constrained reeize: hold down CTRL and
the center is constrained during any resize.
constrained move: hold down SHIFT and
the drag delta is constrained to be a mulitple of ( 0/±1,
0/±1).
 In other words, it snaps to 45 degree increments.

also, we added:
cloned drag: hold down CTRL during a
move, and the request becomes a REQ_CLONE, and the cursor shows a + sign.
 This is used to copy existing objects.

So, the question is, do we need to allow
ways to disable the new features?  for example, if your layout is
not an XY layout, then constraining the center of the object may not make
sense.  If you do not support cloning, then the user would see a NOT
sign when cloning is attempted.  The other concern would be that if
you already implemented cloning, we do not want our implementation to break
your existing one.  thought?
