17.2 Procedures provided in the `font` module

The `font` module defines several procedures and variables for manipulating texts and fonts:

`quotemeta`( | text)

  quoting - Quote letters with special meanings in pychart so that text will display as-is when passed to canvas.show().

      >>> font.quotemeta("foo/bar")
      "foo//bar"

`text_height`( | text)

  Return the total height of the text and the length from the base point to the top of the text box.

`text_width`( | text)

  Return the width of the text in points.

`get_dimension`( | text)

  Return the bounding box of the text, assuming that the left-bottom corner of the first letter of the text is at (0, 0). This procedure ignores /h, /v, and /a directives when calculating the boundingbox; it just returns the alignment specifiers as a part of the return value. The return value is a tuple (width, height, halign, valign, angle).
