/**
* The <code>GL</code> interface is the parent interface for
* the Java(TM) programming language bindings for OpenGL(R) ES 1.0,
* 1.1, and extensions.
*
* <p> The documentation in this interface and its subinterfaces is
* normative with respect to instance variable names and values,
* method names and signatures, and exception behavior. The remaining
* documentation is placed here for convenience and does not replace
* the normative documentation found in the OpenGL ES 1.0 and 1.1
* specifications, relevant extension specifications, and the OpenGL
* specification versions referenced by any of the preceding
* specifications.
*
* <p> A GL object is obtained by calling
* <code>EGLContext.getGL()</code>. The returned object will
* implement either <code>GL10</code> or <code>GL11</code>, plus any
* available extension interfaces (such as <code>GL10Ext</code>,
* <code>GL11Ext</code>, or <code>GL11ExtensionPack</code>). The
* returned object must be cast to the appropriate interface (possibly
* following an <code>instanceof</code> check) in order to call
* GL methods.
*
* <p> A common superinterface is used for OpenGL ES 1.0, OpenGL ES
* 1.1, and Khronos-defined core extensions. In order to determine if
* the implementation supports GL 1.1, call
* <code>glGetString(GL.GL_VERSION)</code>.
*
* <p> Some methods defined in subinterfaces are available only on
* OpenGL ES 1.1. The descriptions of these functions are marked
* "(1.1 only)." Similarly, some methods behave slightly differently
* across OpenGL ES versions. The sections that differ are marked
* "(1.0 only)" and "(1.1 only)" as appropriate. Some methods have an
* additional section marked "1.0 Notes" or "1.1 Notes" that applies
* to the corresponding engine version.
*
* <p> Some extensions are defined as a core part of the OpenGL ES
* specification (they are extensions relative to desktop OpenGL).
* These functions are treated as normal portions of OpenGL ES,
* although they may still be queried as extensions using the normal
* OpenGL ES query mechanisms.
*
* <p> Extensions may allow some arguments to take on values other
* than those listed in this specification. Implementations that
* provide a given extension may pass such values to the underlying
* engine.
*
* <p> Optional profile extensions defined as of the creation of this
* specification may be found in the <code>GL10Ext</code>,
* <code>GL11Ext</code>, and <code>GL11ExtensionPack</code>
* interfaces.
*
* <h3>Vertex Buffer Objects</h3>
*
* <p>VBOs are considered to be enabled if the most recent call to
* <code>glBindBuffer</code> had a target of
* <code>GL_ARRAY_BUFFER</code> and a non-zero <code>buffer</code>
* parameter. When VBOs are enabled, only the variant of the
* <code>gl*Pointer</code> functions that take an integer offset
* (found in the <code>GL11</code> interface) may be called. When
* VBOs are disabled, only the variant of the <code>gl*Pointer</code>
* functions that take a <code>Buffer</code> may be called.
*
* <h3>Clamping</h3>
*
* <p>When method specifies that a value <code>x</code> is clamped to
* a range <code>[A, B]</code>, it means that the value
* <code>min(max(x, A), B)</code> is used in place of the original
* value.
