4/// Draw a pave text.
5/// The text lines are added in order using the AddText method
6/// Line separator can be added using AddLine.
7///
8/// AddText returns a TText corresponding to the line added to the pave. This
9/// return value can be used to modify the text attributes.
10///
11/// Once the TPaveText is build the text of each line can be retrieved as a
12/// TText with GetLine and GetLineWith wich is also useful to modify the text
13/// attributes of a line.
