SR - Set relative character size
SR [ width, height ] [;]
width ; the width of printed characters expressed as a percentage of the x-component of the distance between
P1 and P2.
height ; the height of printed characters expressed as a percentage of the y-component of the distance
between P1 and P2.
This command allows you to specify the size of the character that you print with the LB instruction
relative to the scaling points P1 and P2.
width sets the character width to a percentage of |P2x-P1x| and is a clamped real number. Negative
values of width produce right-to-left mirror image characters
height sets the character height to a percentage of |P2y-P2y| and is a clamped real number. Negative
values of height produce upside-down mirror image character.
If you change the positions of P1 and P2, the character size will change unless the scaling points
remain in the same relative positions.
If you move P2 to the left of, or below P1, characters will appear in mirror image.
If you change the character size, the line width used to draw stick font characters may also change.
If you omit the parameters, the character size is as specified by the most recent SD or AD command.

SL - Character slant
SL [ tan ] [;]
tan - tangent of character slant angle ()
This command determines the slant of characters printed with subsequent LB commands.
is the angle between characters and the vertical. A positive value of ( and tan ) produces forward
sloping characters, while a negative value results in characters which slant backwards.
Values of tan are clamped real numbers.
A value of 0 for tan results in upright characters.
If you omit the parameter, tan is take to be 0 and any characters printed will be upright.
