- * cogl_material_set_blend:
- * @material: A #CoglMaterial object
- * @blend_string: A <link linkend="cogl-Blend-Strings">Cogl blend string</link>
- *   describing the desired blend function.
- * @error: return location for a #GError that may report lack of driver
- *   support if you give separate blend string statements for the alpha
- *   channel and RGB channels since some drivers, or backends such as
- *   GLES 1.1, don't support this feature. May be %NULL, in which case a
- *   warning will be printed out using GLib's logging facilities if an
- *   error is encountered.
- *
- * If not already familiar; please refer <link linkend="cogl-Blend-Strings">here</link>
- * for an overview of what blend strings are, and their syntax.
- *
- * Blending occurs after the alpha test function, and combines fragments with
- * the framebuffer.
-
- * Currently the only blend function Cogl exposes is ADD(). So any valid
- * blend statements will be of the form:
- *
- * |[
- *   &lt;channel-mask&gt;=ADD(SRC_COLOR*(&lt;factor&gt;), DST_COLOR*(&lt;factor&gt;))
- * ]|
- *
- * <warning>The brackets around blend factors are currently not
- * optional!</warning>
- *
- * This is the list of source-names usable as blend factors:
- * <itemizedlist>
- *   <listitem><para>SRC_COLOR: The color of the incoming fragment</para></listitem>
- *   <listitem><para>DST_COLOR: The color of the framebuffer</para></listitem>
- *   <listitem><para>CONSTANT: The constant set via cogl_material_set_blend_constant()</para></listitem>
- * </itemizedlist>
- *
- * The source names can be used according to the
- * <link linkend="cogl-Blend-String-syntax">color-source and factor syntax</link>,
- * so for example "(1-SRC_COLOR[A])" would be a valid factor, as would
- * "(CONSTANT[RGB])"
- *
- * These can also be used as factors:
- * <itemizedlist>
- *   <listitem>0: (0, 0, 0, 0)</listitem>
- *   <listitem>1: (1, 1, 1, 1)</listitem>
- *   <listitem>SRC_ALPHA_SATURATE_FACTOR: (f,f,f,1) where f = MIN(SRC_COLOR[A],1-DST_COLOR[A])</listitem>
- * </itemizedlist>
- *
- * <note>Remember; all color components are normalized to the range [0, 1]
- * before computing the result of blending.</note>
- *
- * <example id="cogl-Blend-Strings-blend-unpremul">
- *   <title>Blend Strings/1</title>
- *   <para>Blend a non-premultiplied source over a destination with
- *   premultiplied alpha:</para>
- *   <programlisting>
- * "RGB = ADD(SRC_COLOR*(SRC_COLOR[A]), DST_COLOR*(1-SRC_COLOR[A]))"
- * "A   = ADD(SRC_COLOR, DST_COLOR*(1-SRC_COLOR[A]))"
- *   </programlisting>
- * </example>
- *
- * <example id="cogl-Blend-Strings-blend-premul">
- *   <title>Blend Strings/2</title>
- *   <para>Blend a premultiplied source over a destination with
- *   premultiplied alpha</para>
- *   <programlisting>
- * "RGBA = ADD(SRC_COLOR, DST_COLOR*(1-SRC_COLOR[A]))"
- *   </programlisting>
- * </example>
- *
- * The default blend string is:
- * |[
- *    RGBA = ADD (SRC_COLOR, DST_COLOR*(1-SRC_COLOR[A]))
- * ]|
- *
- * That gives normal alpha-blending when the calculated color for the material
- * is in premultiplied form.
- *
- * Return value: %TRUE if the blend string was successfully parsed, and the
- *   described blending is supported by the underlying driver/hardware. If
- *   there was an error, %FALSE is returned and @error is set accordingly (if
- *   present).
- *
- * Since: 1.0
- * Deprecated: 1.16: Use cogl_pipeline_set_blend() instead
