Ok never mind, i found the embarassing mistake.
The problem was this:
var settings_dflt=[m1, m2, x1, y1, x2, y2, x3, y3, x4, y4];
settings_dflt = [width/2,height/2,0,0,width,0,width,height,0,height];
I kinda thought the variables in the array would be initialized with the values given to the array. However when i delete the second line and initialize the variables with the starting values before assigning them to the array, everything works fine.
var m1, m2, x1, x2, x3, x4, y1, y2, y3, y4;
m1 = width/2;
m2 = height/2;
x1 = 0;
y1 = 0;
x2 = width;
y2 = 0;
x3 = width;
y3 = height;
x4 = 0;
y4 = height;
var settings_dflt=[m1, m2, x1, y1, x2, y2, x3, y3, x4, y4];
