TTransformation

Description

This transformation class implements a twirl transformation. The amount of twirl can be controlled with the twirl property. The image below shows how a checkerboard pattern were transformed with this transformation. The twirl parameter were set very low for illustrative purposes. With high twirl frequencies (more extreme settings of the twirl property), it is recommended that antialiasing steps are taken (e.g. supersampling).
