Subject: Blit region with GRX ?

I have a routine that plots the results of a calculation using LIBGRX.
GrPlot() is used for each pixel (the colour is determined from the
results of the calculation). I would like to redraw the image with other
information as specified by the user. i.e., store the basic image to
memory and blit it to the screen when necessary. I understand that this
can be done using the GrRegion Class of libgr.a. My question is: Should
(can) I use this with libgrx, or is there another approach? As far as I
understand, libgrx provides GrBitBlt() which can only be used to blit
between/within contexts.

Many thanks in advance.
