GRPCKG (internal routine): Support routine for GRCHAR and GRMARK.
Draw a string of characters.

WINDOW (input, logical): if .TRUE., the plot is windowed in the
current window.
CENTER (input, logical): if .TRUE., the first character of the string
is centered at (X0,Y0); otherwise the bottom left corner of the
first character is placed at (X0,Y0).
ORIENT (input, real): the angle in degrees that the string is to make
with the horizontal, increasing anticlockwise.
ABSXY (input, logical): if .TRUE., (X0,Y0) are absolute device
coordinates; otherwise they are world coordinates (the scaling
transformation is applied).
X0, Y0 (input, real): position of first character (see CENTER).
STRING (input, character): the string of ASCII characters; control
