Would something like this be a correct description? Is adding all those
spaces legal?
geq=equation
generic equation change filter
<equation>
"( p(X\,Y) + p( mod( Y*2-X*2 \,W) \,mod( Y*2+X*2 + sin( (X-Y)
/10 /SW +N ) *SW *20 \,H)) ) /2"
Plus, this is still lacking a description of the constants
("PI", "E", "X", "Y", "W", "H", "N", "SW", "SH").
