===================================
Default text rotation demonstration
===================================

The way Matplotlib does text layout by default is counter-intuitive to some, so
this example is designed to make it a little clearer.

The text is aligned by its bounding box (the rectangular box that surrounds the
ink rectangle).  The order of operations is rotation then alignment.
Basically, the text is centered at your x,y location, rotated around this
point, and then aligned according to the bounding box of the rotated text.

So if you specify left, bottom alignment, the bottom left of the
bounding box of the rotated text will be at the x,y coordinate of the
text.

But a picture is worth a thousand words!
