Gets the extents for a string of text. The extents describe a
user-space rectangle that encloses the "inked" portion of the text
drawn at the origin (0,0) (as it would be drawn by cairo.context.Context.showText
if the cairo graphics state were set to the same font_face,
font_matrix, ctm, and font_options as scaled_font). Additionally,
the x_advance and y_advance values indicate the amount by which the
current point would be advanced by cairo.context.Context.showText.
Note that whitespace characters do not directly contribute to the
size of the rectangle (extents.width and extents.height). They do
contribute indirectly by changing the position of non-whitespace
characters. In particular, trailing whitespace characters are
likely to not affect the size of the rectangle, though they will
affect the x_advance and y_advance values.
