This module contains classes and functions for drawing.

Getting Started With gewel is an introduction to gewel that is useful if you are just getting started.

Sample Code contains numerous examples of the use of classes from this module to create simple animations.

Functions

all_wait_for	Have a group of Drawable objects wait on a single Drawable.
reset_total_device_drawing_time	Reset the total device rendering time.
sync	Ensure that two or more Drawable objects are in sync, meaning that all of them will wait for whichever has the latest completing action before any takes a next action.
total_device_drawing_time	Get the total time spent in rendering at the low level.
walk_text	A subroutine for chopping strings into lines to be rendered.

Background	A background drawable.
BaseScene	A base class for Scene, SceneSequence, and ClipDrawable that provides a little bit of shared base functionality.
BezierDrawable	A Bezier curve parameterized by four points.
BoundedDrawableProtocol	A protocol for drawables that have a location, width, height, and angle of rotation.
BoundedMixin	A mixin that provides common BoundedDrawableProtocol functionality.
Box	A rectangular axis-aligned box.
ClipDrawable	A scene that is a clip of another scene.
ClippedDrawable	A drawable that is a clipped version of another drawable.

ToyTextDrawable	A very simple and all but deprecated text box that should be replaced by TextBox in almost all cases.
TransformedDrawable	A drawable that is a transformed version of another.
TranslatedDrawable	A drawable that is a shifted version of another.
VectorDrawable	The abstract base class for various Drawable classes that are rendered using lines and/or curves, but not, for example, bitmaps.
