<p>A <a class="link" href="cogl-2.0-experimental-Low-level-primitive-textures.html#CoglPrimitiveTexture" title="CoglPrimitiveTexture"><span class="type">CoglPrimitiveTexture</span></a> is a texture that is directly represented
by a single texture on the GPU. For example these could be a
<a class="link" href="cogl-2.0-experimental-2D-textures.html#CoglTexture2D" title="CoglTexture2D"><span class="type">CoglTexture2D</span></a>, <a class="link" href="cogl-2.0-experimental-3D-textures.html#CoglTexture3D" title="CoglTexture3D"><span class="type">CoglTexture3D</span></a> or <a class="link" href="cogl-2.0-experimental-Rectangle-textures-(non-normalized-coordinates).html#CoglTextureRectangle" title="CoglTextureRectangle"><span class="type">CoglTextureRectangle</span></a>. This is
opposed to high level meta textures which may be composed of
multiple primitive textures or a sub-region of another texture such
as <span class="type">CoglAtlasTexture</span> and <a class="link" href="cogl-2.0-experimental-Sliced-Textures.html#CoglTexture2DSliced" title="CoglTexture2DSliced"><span class="type">CoglTexture2DSliced</span></a>.</p>
<p>A texture that implements this interface can be directly used with
the low level <a class="link" href="cogl-2.0-experimental-Primitives.html#cogl-primitive-draw" title="cogl_primitive_draw ()"><code class="function">cogl_primitive_draw()</code></a> API. Other types of textures
need to be first resolved to primitive textures using the
<a class="link" href="cogl-2.0-experimental-High-Level-Meta-Textures.html#CoglMetaTexture" title="CoglMetaTexture"><span class="type">CoglMetaTexture</span></a> interface.</p>
<div class="note">Most developers won't need to use this interface directly but
still it is worth understanding the distinction between high-level
and primitive textures because you may find other references in the
documentation that detail limitations of using
primitive textures.</div>

The Unstable interface level is a warning that these interfaces are  subject to
change without warning and should not be used in unbundled products.

Given such caveats, customer impact need not be a factor when considering
incompatible changes to an Unstable interface in a major or minor release.
Nonetheless, when such changes are introduced, the changes should still be
mentioned in the release notes for the affected release.

mipmap levels after any part of level 0 is updated. The update will
only occur whenever the texture is used for drawing with a texture
filter that requires the lower mipmap levels. An application should
disable this if it wants to upload its own data for the other
levels. By default auto mipmapping is enabled.</p>
