Base class for several text objects.

See TAttText for a list of text attributes or fonts, and also for a discussion on text speed and font quality.

By default, the text is drawn in the pad coordinates system. One can draw in NDC coordinates [0,1] if the function SetNDC is called for a TText object.

Example:

{
   TText *t = new TText(.5,.5,"Hello World !");
   t->SetTextAlign(22);
   t->SetTextColor(kRed+2);
   t->SetTextFont(43);
   t->SetTextSize(40);
   t->SetTextAngle(45);
   t->Draw();
}
