howto: edit the variables to your liking and needs. Then uncomment one of the models in the end of this file, or add your own
 (images have to be in the folder SRC for the provided models). SVG and DXF-Files will work good for this.

Syntax is as following:
 translate([0,-10,0])    logo("SRC/icinga.svg",3.5);
 ^ move logo [x,y,z](optional) ^ filename      ^ scaling-factor (1==100%), depending on source file
