Inserts a shape from a shape file that has been loaded using LOAD.
Code 7: Subshape
Code 7 draws the subshape number given by the next byte.
For a non-Unicode font the specification byte following code 7 is a shape
number from 1 to 255. For a Unicode font, code 7 is followed by a Unicode
shape number from 1 to 65535. Unicode shape numbers should be counted
as two bytes (for specific information about the differences between Unicode
and non-Unicode fonts, see
Unicode Font Descriptions on page 180).
The shape with that number (in the same shape file) is drawn at this time.
Draw mode is not reset for the new shape. When the subshape is complete,
drawing the current shape resumes.
