_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.

rrrreeeeccccttttzzzzoooooooommmm specifies independent _x and _y zoom factors that rrrreeeeccccttttccccooooppppyyyy,
rrrreeeeccccttttwwwwrrrriiiitttteeee, and llllrrrreeeeccccttttwwwwrrrriiiitttteeee use. rrrreeeeccccttttzzzzoooooooommmm 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 rrrreeeeccccttttzzzzoooooooommmm((((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.
