<BLOCKQUOTE>Pure virtual base class for drawable Geometry. Contains no drawing primitives
directly, these are provided by subclasses such as GeoSet. State attributes
for a Drawable are maintained in StateSet which the Drawable maintains
a referenced counted pointer to. Both Drawable's and StateSet's can
be shared for optimal memory usage and graphics performance.
<P>Subclasses should provide an instance of getStats(Statistics *st) if the subclass
contains drawing primitives. This member function should add the primitives it
draws into the Statistics class; for example add the number of quads, triangles etc
created. For an example see GeoSet.cpp:
getStats(osgUtil::Statistics *stat).
Failure to implement this routine will only result in the stats displayed for
your drawable being wrong.
Another example is in the InfinitePlane class- this draws a normal geoset AND
its own special set of quads, so this case of getPrims calls:
the normal geoset stats gs->getStats(..), and then adds the number of quads
rendered directly (it is rendered in a display list, but we do know how many
quads are in the display list).</BLOCKQUOTE>

<DD>draw OpenGL primitives.
If the drawable has _useDisplayList set to true then use an OpenGL display
list, automatically compiling one if required.
Otherwise call drawImmediateMode().
Note, draw method should *not* be overridden in subclasses as it
manages the optional display list.
