  57             Texturing maps a portion of a specified texture image
  58             onto each graphical primitive for which texturing is enabled.
  59             To enable and disable one-dimensional texturing, call <a href="glEnable.xml"><span class="citerefentry"><span class="refentrytitle">glEnable</span></span></a>
  60             and <a href="glDisable.xml"><span class="citerefentry"><span class="refentrytitle">glDisable</span></span></a> with argument <code class="constant">GL_TEXTURE_1D</code>.
  61         </p><p>
  62             Texture images are defined with <code class="function">glTexImage1D</code>.
  63             The arguments describe the parameters of the texture image,
  64             such as width,
  65             width of the border,
  66             level-of-detail number
  67             (see <a href="glTexParameter.xml"><span class="citerefentry"><span class="refentrytitle">glTexParameter</span></span></a>),
  68             and the internal resolution and format used to store the image.
  69             The last three arguments describe how the image is represented in
  70             memory.
  71         </p><p>
  72             If <em class="parameter"><code>target</code></em> is <code class="constant">GL_PROXY_TEXTURE_1D</code>, no data is read from <em class="parameter"><code>data</code></em>, but
  73             all of the texture image state is recalculated, checked for
  74             consistency, and checked against the implementation's capabilities.
  75             If the implementation cannot handle a texture of the
  76             requested texture size, it sets all of the image state to 0,
  77             but does not generate an error (see <a href="glGetError.xml"><span class="citerefentry"><span class="refentrytitle">glGetError</span></span></a>). To query for an
  78             entire mipmap array, use an image array level greater than or equal to
  79             1.

  81             If <em class="parameter"><code>target</code></em> is <code class="constant">GL_TEXTURE_1D</code>,
  82             data is read from <em class="parameter"><code>data</code></em> as a sequence of signed or unsigned bytes,

  84             or longs,
  85             or single-precision floating-point values,
  86             depending on <em class="parameter"><code>type</code></em>.
  87             These values are grouped into sets of one,
  88             two,
  89             three,

  91             depending on <em class="parameter"><code>format</code></em>,
  92             to form elements.
  93             Each data byte is treated as eight 1-bit elements,
  94             with bit ordering determined by <code class="constant">GL_UNPACK_LSB_FIRST</code>
  95             (see <a href="glPixelStore.xml"><span class="citerefentry"><span class="refentrytitle">glPixelStore</span></span></a>).

  99             specified, <em class="parameter"><code>data</code></em> is treated as a byte offset into the buffer object's data store.
 100         </p><p>
 101             The first element corresponds to the left end of the texture array.
 102             Subsequent elements progress left-to-right through the remaining texels
 103             in the texture array.

 297             update and recompute its best match for the requested storage resolution

 301             A one-component texture image uses only the red component of the RGBA

 303             A two-component image uses the R and A values.

 307             Image-based shadowing can be enabled by comparing texture r coordinates to depth texture values to generate a boolean result.  See <a href="glTexParameter.xml"><span class="citerefentry"><span class="refentrytitle">glTexParameter</span></span></a> for details on texture comparison.
