Sets a hint for the theme to draw even/odd rows in the tree_view
with different colors, also known as "zebra striping".
This function tells the GTK+ theme that the user interface for your
application requires users to read across tree rows and associate
cells with one another.
Do not use it just because you prefer the appearance of the ruled
tree; that’s a question for the theme. Some themes will draw tree
rows in alternating colors even when rules are turned off, and
users who prefer that appearance all the time can choose those
themes. You should call this function only as a semantic hint to
the theme engine that your tree makes alternating colors useful
from a functional standpoint (since it has lots of columns,
generally).
