			<tt>gluBuild2DMipmaps</tt> builds a series of prefiltered two-dimensional texture maps of decreasing
			resolutions called a mipmap. This is used for the antialiasing of texture-mapped primitives.
		</p><p>
			A return value of zero indicates success, otherwise a GLU error code is returned (see <a href="gluErrorString.3G.xml"><tt>gluErrorString</tt></a>).
		</p><p>
			Initially, the <i><tt>width</tt></i> and <i><tt>height</tt></i> of <i><tt>data</tt></i> are
			checked to see if they are a power of 2. If not, a copy of <i><tt>data</tt></i> (not
			<i><tt>data</tt></i>), is scaled up or down to the nearest power of 2. This copy will be used for subsequent
			mipmapping operations described below. (If <i><tt>width</tt></i> or <i><tt>height</tt></i> is exactly
			between powers of 2, then the copy of <i><tt>data</tt></i> will scale upwards.) For example, if
			<i><tt>width</tt></i> is 57 and <i><tt>height</tt></i> is 23 then a copy of <i><tt>data</tt></i>
			will scale up to 64 in <i><tt>width</tt></i> and down to 16 in depth, before mipmapping takes place.
		</p><p>
			Then, proxy textures (see <a href="glTexImage2D.3G.xml">glTexImage2D</a>) are used to determine if the implementation can fit the requested texture. If not, both dimensions are
			continually halved until it fits. (If the OpenGL version is &#8804; 1.0, both maximum texture dimensions are clamped to
			the value returned by <a href="glGet.3G.xml"><tt>glGetIntegerv</tt></a> with the argument
			<tt>GL_MAX_TEXTURE_SIZE</tt>.)
		</p><p>
			Next, a series of mipmap levels is built by decimating a copy of <i><tt>data</tt></i> in half along both
			dimensions until size <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll">
					<mml:mrow>
						<mml:mn>1</mml:mn>
						<mml:mo>×</mml:mo>
						<mml:mn>1</mml:mn>
					</mml:mrow>
				</mml:math> is reached. At each level, each texel in the halved mipmap level is an average of the corresponding
			four texels in the larger mipmap level. (In the case of rectangular images, the decimation will ultimately reach an
			<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll">

				</mml:math> configuration. Here, two texels are averaged instead.)
		</p><p>
			<a href="glTexImage2D.3G.xml"><tt>glTexImage2D</tt></a> is called to load each of these mipmap levels. Level 0 is a copy
			of <i><tt>data</tt></i>. The highest level is <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll">
