  49         <para>
  50             <function>glDeleteTextures</function> deletes <parameter>n</parameter> textures named by the elements of the array <parameter>textures</parameter>.
  51             After a texture is deleted, it has no contents or dimensionality,
  52             and its name is free for reuse (for example by <citerefentry><refentrytitle>glGenTextures</refentrytitle></citerefentry>).
  53             If a texture that is currently bound is deleted, the binding reverts
  54             to 0 (the default texture).
  55         </para>
  56         <para>
  57             <function>glDeleteTextures</function> silently ignores 0's and names that do not correspond to
  58             existing textures.
