 * These callbacks are used by the tessellation object to describe how a

 *
 * <b>GLU_TESS_BEGIN</b>
 * <UL>
 *   The begin callback is invoked like {@link net.java.games.jogl.GL#glBegin
 *   glBegin} to indicate the start of a (triangle) primitive. The method
 *   takes a single argument of type int. If the
 *   <b>GLU_TESS_BOUNDARY_ONLY</b> property is set to <b>GL_FALSE</b>, then
 *   the argument is set to either <b>GL_TRIANGLE_FAN</b>,
 *   <b>GL_TRIANGLE_STRIP</b>, or <b>GL_TRIANGLES</b>. If the
 *   <b>GLU_TESS_BOUNDARY_ONLY</b> property is set to <b>GL_TRUE</b>, then the

 *
 * <PRE>

 *
 * <b>GLU_TESS_BEGIN_DATA</b>
 * <UL>
 *   The same as the <b>GLU_TESS_BEGIN</b> callback except

 *
 * <PRE>

 *
 * <b>GLU_TESS_EDGE_FLAG</b>
 * <UL>
 *   The edge flag callback is similar to
 *   {@link net.java.games.jogl.GL#glEdgeFlag glEdgeFlag}. The method takes
 *   a single boolean boundaryEdge that indicates which edges lie on the
 *   polygon boundary. If the boundaryEdge is <b>GL_TRUE</b>, then each vertex
 *   that follows begins an edge that lies on the polygon boundary, that is,
 *   an edge that separates an interior region from an exterior one. If the
 *   boundaryEdge is <b>GL_FALSE</b>, then each vertex that follows begins an
 *   edge that lies in the polygon interior. The edge flag callback (if
 *   defined) is invoked before the first vertex callback.<P>
 *
 *   Since triangle fans and triangle strips do not support edge flags, the
 *   begin callback is not called with <b>GL_TRIANGLE_FAN</b> or
 *   <b>GL_TRIANGLE_STRIP</b> if a non-null edge flag callback is provided.
 *   (If the callback is initialized to null, there is no impact on
 *   performance). Instead, the fans and strips are converted to independent
 *   triangles. The method prototype for this callback is:
 * </UL>
 *
 * <PRE>
 *         void edgeFlag(boolean boundaryEdge);</PRE>
 *
 * <b>GLU_TESS_EDGE_FLAG_DATA</b>
 * <UL>
 *   The same as the <b>GLU_TESS_EDGE_FLAG</b> callback except that it takes
 *   an additional reference argument. This reference is identical to the
 *   opaque reference provided when
 *   {@link net.java.games.jogl.GLU#gluTessBeginPolygon gluTessBeginPolygon}
 *   was called. The method prototype for this callback is:
 * </UL>
 *
 * <PRE>
 *         void edgeFlagData(boolean boundaryEdge, Object polygonData);</PRE>
 *
 * <b>GLU_TESS_VERTEX</b>
 * <UL>
 *   The vertex callback is invoked between the begin and end callbacks. It is
 *   similar to {@link net.java.games.jogl.GL#glVertex3f glVertex3f}, and it
 *   defines the vertices of the triangles created by the tessellation
 *   process. The method takes a reference as its only argument. This
 *   reference is identical to the opaque reference provided by the user when
 *   the vertex was described (see

 *
 * <b>GLU_TESS_END</b>
 * <UL>
 *   The end callback serves the same purpose as
 *   {@link net.java.games.jogl.GL#glEnd glEnd}. It indicates the end of a
 *   primitive and it takes no arguments. The method prototype for this
 *   callback is:
 * </UL>

 *

 * </UL>
 *
 * <PRE>
 *         void endData(Object polygonData);</PRE>
 *
 * <b>GLU_TESS_COMBINE</b>
 * <UL>
 *   The combine callback is called to create a new vertex when the
 *   tessellation detects an intersection, or wishes to merge features. The
 *   method takes four arguments: an array of three elements each of type
 *   double, an array of four references, an array of four elements each of
 *   type float, and a reference to a reference. The prototype is:
 * </UL>

 * <PRE>

 *                      float[] weight, Object[] outData);</PRE>
 *
 * <UL>
 *   The vertex is defined as a linear combination of up to four existing
 *   vertices, stored in <i>data</i>. The coefficients of the linear
 *   combination are given by <i>weight</i>; these weights always add up to 1.
 *   All vertex pointers are valid even when some of the weights are 0.
 *   <i>coords</i> gives the location of the new vertex.<P>
 *
 *   The user must allocate another vertex, interpolate parameters using
 *   <i>data</i> and <i>weight</i>, and return the new vertex pointer
 *   in <i>outData</i>. This handle is supplied during rendering callbacks.
 *   The user is responsible for freeing the memory some time after
 *   {@link net.java.games.jogl.GLU#gluTessEndPolygon gluTessEndPolygon} is
 *   called.<P>
 *
 *   For example, if the polygon lies in an arbitrary plane in 3-space, and a
 *   color is associated with each vertex, the <b>GLU_TESS_COMBINE</b>
 *   callback might look like this:
 * </UL>
 * <PRE>

 *
 *   To understand how the winding rule works, consider that the input
 *   contours partition the plane into regions.  The winding rule determines
 *   which of these regions are inside the polygon.<P>
 *
 *   For a single contour C, the winding number of a point x is simply the
 *   signed number of revolutions we make around x as we travel once around C
 *   (where CCW is positive).  When there are several contours, the individual
 *   winding numbers are summed.  This procedure associates a signed integer
 *   value with each point x in the plane.  Note that the winding number is
 *   the same for all points in a single region.<P>
 *
 *   The winding rule classifies a region as "inside" if its winding number
 *   belongs to the chosen category (odd, nonzero, positive, negative, or
 *   absolute value of at least two).  The previous GLU tesselator (prior to
 *   GLU 1.2) used the "odd" rule.  The "nonzero" rule is another common way

 *   operations.
 * </UL>
 * <BR><b>GLU_TESS_BOUNDARY_ONLY</b>
 * <UL>
 *   Is a boolean value ("value" should be set to GL_TRUE or GL_FALSE). When
 *   set to GL_TRUE, a set of closed contours separating the polygon interior
 *   and exterior are returned instead of a tessellation.  Exterior contours
 *   are oriented CCW with respect to the normal; interior contours are
 *   oriented CW. The <b>GLU_TESS_BEGIN</b> and <b>GLU_TESS_BEGIN_DATA</b>
 *   callbacks use the type GL_LINE_LOOP for each contour.
 * </UL>
 * <BR><b>GLU_TESS_TOLERANCE</b>
 * <UL>
 *   Specifies a tolerance for merging features to reduce the size of the
 *   output. For example, two vertices that are very close to each other
 *   might be replaced by a single vertex.  The tolerance is multiplied by the
 *   largest coordinate magnitude of any input vertex; this specifies the
 *   maximum distance that any feature can move as the result of a single
 *   merge operation.  If a single feature takes part in several merge
 *   operations, the toal distance moved could be larger.<P>
 *

/**
 * Returns true if the specified GLU core- or extension-function can be
 * successfully used through this GLU instance. By "successfully" we mean
 * that the function is both <i>callable</i> on the machine running the
 * program and <i>available</i> on the current display.<P>
 *
 * A GLU function is <i>callable</i> if it is a GLU core- or extension-function
 * that is supported by the underlying GLU implementation. The function is
 * <i>available</i> if the OpenGL implementation on the display meets the
 * requirements of the GLU function being called (because GLU functions utilize
 * OpenGL functions). <P>
 *
 * Whether or not a GLU function is <i>callable</i> is determined as follows:
 * <ul>
 *   <li>If the function is a GLU core function (i.e., not an
 *   extension), <code>gluGetString(GLU_VERSION)</code> is used to determine the
 *   version number of the underlying GLU implementation on the host.
 *   then the function name is cross-referenced with that specification to
 *   see if it is part of that version's specification.
 *
 *   <li> If the function is a GLU extension, the function name is
 *   cross-referenced with the list returned by
 *   <code>gluGetString(GLU_EXTENSIONS)</code> to see if the function is one of
 *   the extensions that is supported by the underlying GLU implementation.
 * </ul>
 *
 * Whether or not a GLU function is <i>available</i> is determined as follows:
 * <ul>
 *   <li>If the function is a GLU core function then the function is first
 *   cross-referenced with the GLU specifications to find the minimum GLU
 *   version required to <i>call</i> that GLU function. Then the following table
 *   is consulted to determine the minimum GL version required for that version
 *   of GLU:
 *   <ul>
 *   <li> GLU 1.0 requires OpenGL 1.0
 *   <li> GLU 1.1 requires OpenGL 1.0
 *   <li> GLU 1.2 requires OpenGL 1.1
 *   <li> GLU 1.3 requires OpenGL 1.2
 *   </ul>
 *   Finally, <code>glGetString(GL_VERSION)</code> is used to determine the
 *   highest OpenGL version that both host and display support, and from that it
 *   is possible to determine if the GL facilities required by the GLU function
 *   are <i>available</i> on the display.
 *
 *   <li> If the function is a GLU extension, the function name is
 *   cross-referenced with the list returned by
 *   <code>gluGetString(GLU_EXTENSIONS)</code> to see if the function is one of
 *   the extensions that is supported by the underlying GLU implementation.
 * </ul>
 *
 * <b>NOTE:</b>The availability of a function may change at runtime in
 * response to changes in the display environment. For example, when a window
 * is dragged from one display to another on a multi-display system, or when
 * the properties of the display device are modified (e.g., changing the color
 * depth of the display). Any application that is concerned with handling
 * these situations correctly should confirm availability after a display
 * change before calling a questionable OpenGL function. To detect a change in
 * the display device, please see {@link
 * GLEventListener#displayChanged(GLDrawable,boolean,boolean)}.
 *
 * @param gluFunctionName the name of the OpenGL function (e.g., use
 * "gluNurbsCallbackDataEXT" to check if the <code>
 * gluNurbsCallbackDataEXT(GLUnurbs, GLvoid)</code> extension is available).
