you just have to imagin that the 4 values you give are a Rectangle where
you draw a text ... and then the Alignment value tell how to align text in
The text rectangle is not clipped so the text is drawn outside the
rectangle if this one is too small to contain it. This allow to draw text
even if you not give the height/width values
By default the value of alignment is topleft.
