- _x_f_a_c_t_o_r expects the multiplier of the rectangle in the x direction.
-
- _y_f_a_c_t_o_r expects the multiplier of the rectangle in the y direction.

- rrrreeeeccccttttzzzzoooo specifies independent _x and _y zoom factors that rrrreeeeccccttttccccoooo, rrrreeeeccccttttwwwwrrrr,
- and llllrrrreeeeccccttttwwww use. rrrreeeeccccttttzzzzoooo scales the source image by the numbers specified
- by _x_f_a_c_t_o_r and _y_f_a_c_t_o_r. If rrrreeeeccccttttzzzzoooo((((2222....0000,,,, 3333....0000)))) is called, and the following
- rectangle is copied:
-
- 1 3
- 5 7
-
- the copy will be:
-
- 1 1 3 3
- 1 1 3 3
- 1 1 3 3
- 5 5 7 7
- 5 5 7 7
- 5 5 7 7

- Although zoom factors are specified as floating point values, some
- graphics systems do not support fractional zooms. These systems round
- each floating point zoom factor to the nearest integer value. Systems
- that do support fractional zoom replicate source image pixels when the
- zoom factor is greater than 1.0, and decimate the source image when the
- zoom factor is less than 1.0.
-
- By default, _x_f_a_c_t_o_r and _y_f_a_c_t_o_r are 1.0.

- This subroutine is available only in immediate mode.
-
- IRIS-4D G, GT, and GTX models, the Personal Iris, Iris Entry, Indy, XL,
- XS, XS24, XZ, Elan, and Extreme systems do not support fractional zoom.
- The Personal Iris, XS, XS24, XZ, Elan, and Extreme systems do not support
- zoom factors greater than 255.0.
