Notes:
This operator subtracts the second operand from the first one. The resulting data type is the biggest data type of op1 and op2.
If you subtract a color c2=(r2,g2,b2,a2) from another color c1=(r1,g1,b1,a1), then the operation is performed per component, i.e. c3=c1-c2=rgba(r1-r2,g1-g2,b1-b2,a1-a2).
Examples:
3-4 = -1
x-y
