<para>
<function>glTexStorage3DMultisample</function> and
<function>glTextureStorage3DMultisample</function> specify the
storage requirements for
a two-dimensional multisample array texture. Once a texture is specified with this
command, its format and dimensions become immutable unless it is a proxy
texture. The contents of the image may still be modified, however, its storage requirements
may not change. Such a texture is referred to as an <emphasis>immutable-format</emphasis>
texture.
</para>
<para>
<parameter>samples</parameter> specifies the number of samples to be used for the texture
and must be greater than zero and less than or equal to the value of <constant>GL_MAX_SAMPLES</constant>.
<parameter>internalformat</parameter> must be a color-renderable, depth-renderable, or stencil-renderable format.
<parameter>width</parameter> and <parameter>height</parameter> specify the width and height,
respectively, of the texture and <parameter>depth</parameter> specifies the depth (or the number of layers)
of the texture. If <parameter>fixedsamplelocations</parameter> is <constant>GL_TRUE</constant>,
the image will use identical sample locations and the same number of samples for all texels in the image,
and the sample locations will not depend on the internal format or size of the image.
