this grid generates 420 points,
but it is overridable like this:
points = 400
A => A+BF+BF
B => BF
formula = (x - y) / i - sin(t)
order = 4
angle = 90
A => BF-F-BFFFC-F-FC+F+BF-F-BFFFC-F-FC
B => BFFFC-F-FC+F+B
C => C+F+BF-F-BFFFC
formula = sin(i / x / y - t)
order = 6
angle = 120
A => F+F+F
F => F-F+F
formula = sin(log(i) - t)
