I would like to take an ICON resource, read it in and somehow store it as
a Region so that I can take advantage of the "Quickness" of regions in 
comparison to icons.  Basically I do the following:

/* this to get it initially */
GetIcon(theIcon,iconID);
SetRect(theRect,left,top,right,bottom);
PlotIcon(theRect,theIcon);

/* and this to move it around */
EraseRect(theRect);
OffsetRect(theRect, horiz, vert);
PlotIcon(theRect,theIcon);

in order to move the icon around on the screen.

It just seems that it would be much faster to do this:

/* this to get it initially */
GetIcon(theIcon,iconID);
iconRgn:= NewRgn;
OpenRgn;
SetRect(theRect,left,top,right,bottom);
PlotIcon(theRect,theIcon); 		/* does this work? it didn't for me */
CloseRgn(iconRgn);

/* and this to move it around */
EraseRgn(iconRgn);
OffsetRgn(iconRgn,horiz,vert);
FrameRgn(iconRgn);




I would think this possible, but what am I doing wrong?

Is there a better way to do this?  It seems pretty cumbersome, but I found
no better "obvious" way.  Plus, I just started and haven't become accustomed
to regions, bitmaps, etc...

Please e-mail any advice.

Thank you,
