Adds a region to context, so posterior calls to
Style.contextGet or any of the gtk_render_*()
functions will make use of this new region for styling.
In the CSS file format, a gtk.TreeView defining a “row”
region, would be matched by:
|[ <!-- language="CSS" -->
treeview row { ... }
Pseudo-classes are used for matching `flags`, so the two
following rules:
|[ <!-- language="CSS" -->
treeview row:nth-child(even) { ... }
treeview row:nth-child(odd) { ... }
would apply to even and odd rows, respectively.
Region names must only contain lowercase letters
and “-”, starting always with a lowercase letter.
