Pixel Math
====================
This option allows you to perform simple mathematical operations on your
images. You can: add a constant to every pixel, subtract a constant from
every pixel, multiply every pixel by a non-negative real number, divide
every pixel by a non-negative, non-zero real number. The multiply and
divide operations use extended precision floating point (18 significant
digits), but the final result is rounded to the nearest integer. Results
greater than 65535 are clamped at 65535 as are results less than zero
clamped at zero.
