Adds the logical vertex \a lv to this section of a display list.
Two QLogicalVertex instances a and b are treated as being duplicates for
the purpose of smoothing, if \c{qFuzzyCompare(a.vertex(), b.vertex())} is
true
All duplicate occurrences of a vertex are coalesced, that is replaced
by a GL index referencing the one copy.
In order to draw \a lv as part of a smooth continuous surface, with
no distinct edge, duplicates of vertex \a lv are coalesced into one
(within this section) and the normal for that one set to the average of
the incoming unique normals.
The incoming vertex \a lv is not treated as a duplicate if \a lv has
different texture coordinates or attributes. This occurs for example
in the case of a texture seam, where two different texture coordinates
are required at the same point on the geometry.
In that case a new duplicate vertex is added to carry the unique
texture coordinates or attributes. When new vertex copies are added in
this way all copies receive the averaged normals.
Call this function to add the vertices of a smooth face to the section
of a display list, or use:
\code
myDisplayList->newSection(QGLBuilder::Smooth);
myDisplayList->addTriangle(a, b, c);
\endcode
In smooth surfaces, the vertex and its normal is only sent to the
graphics hardware once (not once per face), thus smooth geometry may
consume fewer resources.

Add the logical vertex \a lv to this section of a display list.
The vertex will be drawn as a distinct edge, instead of just part of a
continuous smooth surface. To acheive this the vertex value of \a lv
is duplicated for each unique normal in the current section.
Note that duplication is only for unique normals: if a vertex is already
present with a given normal it is coalesced and simply referenced by index.
As for appendSmooth() vertices are not coalesced in this way if \a lv
has a different texture coordinate or attribute than its duplicate.
This function is used to add the vertices of a faceted face to the list:
\code
myDisplayList->newSection(QGLBuilder::Faceted);
myDisplayList->addVertex(lv);
\endcode
In faceted surfaces, the vertex is sent to the graphics hardware once for
each normal it has, and thus may consume more resources.
