"""Draw the faces of a volmesh.
Parameters
----------
volmesh : compas.datastructures.VolMesh
A volmesh object.
keys : list (None)
A list of edge keys identifying which faces to draw.
Default is to draw all faces.
color : str, tuple, dict (None)
The color specififcation for the faces.
Colors should be specified in the form of a string (hex colors) or as a tuple of RGB components.
To apply the same color to all faces, provide a single color specification.
Individual colors can be assigned using a dictionary of key-color pairs.
Missing keys will be assigned the default vertex color (``self.defaults['vertex.color']``).
Default is use the color of the parent layer.
layer : str (None)
The layer in which the faces are drawn.
Default is to draw in the current layer.
clear_layer : bool (False)
Clear the drawing layer.
redraw : bool (True)
Redraw the view after adding the faces.
Examples
--------
>>> volmesh_draw_faces(volmesh)
>>> volmesh_draw_faces(volmesh, keys=volmesh.faces_on_boundary())
>>> volmesh_draw_faces(volmesh, color='#00ff00')
>>> color = {key: (('#ff0000') if volmesh.vertex_is_on_boundary(key) else ('#00ff00')) for key in volmesh.faces()}
>>> volmesh_draw_faces(volmesh, color=color)
