Consider two variables, W1 and W2, which are true for pixels between the appropriate left and right bounds as set in $2126-$2129 and false otherwise. Then, you have the following possibilities: (replace "W#" with "~W#", depending on the Inversion settings of $2123-$2125) Neither window enabled => nothing masked. One window enabled => Either W1 or W2, as appropriate. Both windows enabled => W1 op W2, where "op" is as above. Where the function is true, the BG will be masked.
See the section "WINDOWS" below for more details.
