In the Revolution goc, "grc" means "graphic" not "image", so I'm 
confused.  I don't know what it is for.

This is only for the outer group.  If you don't use the outer group, 
then don't bother.

For me, I have trouble working with locking a location and locking the 
size being the same, and I prefer to make those independent.

Here is how I did this:

1.  I created an image using "Import as Control...".

2.  I grouped this and named this "Inner Group".  (If you do a bunch of 
custom control scripting then use a smaller name, because those should 
be me-relative.)

3.  I set the margins of the group to 0 (Text Formatting pane).  This 
has to be done before steps 4 and 5.  (Bug?)

4.  I went to the Size and Position pane of the property inspector.  I 
set the size to 200 X 200 and checked lock size and position.  Use 
whatever you want for the size; you can change it later.

5.  I went to the Basic Properties pane and turned on the scroll bars.  
On OS X, change the scroll width from 16 to 15.

6.  At this point it has no border and you can't move it.

7.  Make sure Select Grouped is off.  Select the group.  In the message 
box execute "group".  That creates a new group.  (The group button will 
try to ungroup, so don't use it.)  Name it "Scrollable Image".  You can 
now move this control in your card layout, but if you change cards it 
will not resize.

8.  Now for the border.  I set the margins of the custom control (group 
"Scrollable Image") to 0.  On the Basic Properties pane I turned off 
3d, and turned on the border.  This border will grow out from the inner 
group and will not cover the image.  The size of the custom control is 
exactly the size of the inner group plus (double) the borders.

Ta-dah!

(I deleted a bunch of stuff of interest only to weirdos like me, such 
as custom properties.)
