Drawable provides a convenient interface for preparing vector, image, or text arguments.
This enumeration lists specific character repertories (i.e., charsets), and not text encoding methods (e.g., UTF-8, UTF-16, etc.).
The font weight can be specified as one of 100, 200, 300, 400, 500, 600, 700, 800, or 900, or one of the following constants.
GradientDirection determines if the gradient fades from top to bottom or from left to right.
This defines a Gradient used when drawing.
