Normalize width of layers

$$nominalValue/width*100$$

nominal = 100
offset = 900; // connect to slider control
threshold = 0;
//
swidth = thisLayer.sourceRectAtTime().width;

svalue = nominal/swidth;

// conditional 
if(swidth>threshold){
    [svalue,svalue,svalue]*offset
}

sHeight=height/logo.height;
sWidth=width/logo.width;
