_d_o_t_g_e_n generates an image of two crossed sinusoidal wave patterns. The
output image can be used as input to thresh to create halftoned images.
The output of _d_o_t_g_e_n is a square image size pixels on a side. scalex and
scaley are floating point values that can be used to change the density
and rotation of the dot pattern. If they are both integers, the output
image will match up with its self when it tiles the plane. The ----aaaa option
causes _d_o_t_g_e_n to take the absolute value of the sum of the two sinusoids.
