added arms to Spongebob through the edge renderings.

[NiklasRentzCAU]

This graph now looks a lot more like Spongebob with new little arms!
Default values: on, Style: Spongebob.

Also works for Splines and for elkt Graphs, with or without edge directions.

In Eclipse with Piccolo, only the outer black line of the arm is drawn and not the yellow inner part. I will not further investigate this issue, as it is deeply ingrained in the Piccolo configuration and implementation of KLighD.

properties:
    org.eclipse.elk.direction=RIGHT
    // org.eclipse.elk.edgeRouting=SPLINES

knode a {
    size: width = 50 height = 50
    kedge (->b)
    kedge (->c)
    klabel ""
}

knode b {
    size: width = 50 height = 50
    klabel ""
}

knode c {
    size: width = 50 height = 50
    kedge (->d)
    kedge (->e)
    klabel ""
}

knode d {
    size: width = 50 height = 50
    kedge (->a)
    klabel ""
}

knode e {
    size: width = 50 height = 50
    klabel ""
    kedge (->a)
}
