SUBGROB_P(srcGRB [ ,x1, y1, x2, y2], trgtGRB)
Sets trgtGRB to be a copy of the area of srcGRB between
points x1,y1 and x2,y2.
srcGRB can be any of the graphics variables and is
optional. The default is G0.
trgtGRB can be any of the graphics variables except G0.
x2, y2 are optional and if not specified will be the bottom
