variable that is used in conjunction with opcodes that are using relative
logical coordinates.

Updates CurrentPoint
Origin variable
X,Y The new logical coordinate origin to assign to the CurrentPoint
variable
Details
Sets the CurrentPoint variable (also called the origin) to an
absolute logical coordinate. This opcode is often used just prior to 16-bit
relative-coordinate drawing primitives to define the 16-bit relative space
within the 32-bit absolute space.. The CurrentPoint variable is
used by drawing opcodes as an offset to convert relative logical coordinates
to absolute logical coordinates.
Default
The default CurrentPoint is set at the logical coordinate space
origin (0,0).
