#displayOn:at: uses copyBits with the combination rule "Form over", which simply copies the form over the specified bitmap. The rule to use depends upon your particular needs. Perhaps:
(Form dotOfSize: 20) displayOn: Display
at: 200 at 200
clippingBox: Display boundingBox
rule: Form and
fillColor: nil
Many other combinations are possible, depending upon the particular results desired.
