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