Of course: as you don't specify any alignment, top left alignment is 
assumed (or top right if you use a rtl language), and so only the X and 
Y drawing coordinates have an impact of the text drawing position.

The Alignment argument is one of the Align class constants, and tells 
where the text is drawn inside the specified rectangle. I don't see what 
is utterly complicated here...
