further access.
EditMode Tessellation
^^^^^^^^^^^^^^^^^^^^^
When writing scripts that operate on editmode data you will normally want to re-calculate the tessellation after
running the script, this needs to be called explicitly.
The BMesh its self does not store the triangulated faces, they are stored in the :class:`bpy.types.Mesh`,
to refresh tessellation faces call :class:`bpy.types.Mesh.calc_tessface`.
