.SH DESCRIPTION
.sp 1
.IP XrAddPt
Add the coordinates of 
.I srcPt
to the coordinates of
.I dstPt,
and return the result in
.I dstPt.
.IP XrSubPt
Subtract the coordinates of 
.I srcPt
from the coordinates of 
.I dstPt,
and return the result in 
.I dstPt.
.IP XrSetPt
Assign the two coordinates to a variable of type POINT.
.IP XrOffsetPt
Change the values of the point structure
.I pt
by adding the
.I x
and
.I y
offsets to the members of
.I pt.
.IP XrCopyPt
Copy 
.I srcPt
into 
.I dstPt.
.IP XrEqualPt
Compare the two points and return 
.B TRUE
if they are equal or 
.B FALSE
if not.
