For example, instead of using @code{cmf_10deg}, you

+@item lower_resolution(x, y)
+Emulate low resolution. @code{x} is the number of

+@code{y} does the same thing as @code{x}, except
+on the output axis rather than the encoding axis.

+@item lower_resolution(rx, ry, gx, gy, bx, by)
+This works the same way as @code{lower_resolution(x, y)},
+except the subpixels are controlled individually.
+@code{rx} and @code{ry} are @code{x} and @code{y}
+for the red subpixel, and analogously for @code{gx}
+and @code{gy} for green, and @code{bx} and @code{by}
+for blue.
