-    Returns width and height (in pixels) of given text if rendered in font with
-    provided direction, features, and language.
-
-    :param text: Text to measure.
-
-    :param direction: Direction of the text. It can be 'rtl' (right to
-                      left), 'ltr' (left to right) or 'ttb' (top to bottom).
-                      Requires libraqm.

-
-    :param features: A list of OpenType font features to be used during text
-                     layout. This is usually used to turn on optional
-                     font features that are not enabled by default,
-                     for example 'dlig' or 'ss01', but can be also
-                     used to turn off default font features for
-                     example '-liga' to disable ligatures or '-kern'
-                     to disable kerning.  To get all supported

-    :param language: Language of the text. Different languages may use

-                     the font which language the text is in, and to apply the
-                     correct substitutions as appropriate, if available.
-                     It should be a `BCP 47 language code

-
-    Create a bitmap for the text.
-
-    If the font uses antialiasing, the bitmap should have mode “L” and use a
-    maximum value of 255. Otherwise, it should have mode “1”.
-
-    :param text: Text to render.
-    :param mode: Used by some graphics drivers to indicate what mode the
-                 driver prefers; if empty, the renderer may return either
-                 mode. Note that the mode is always a string, to simplify
