<p>The basic intention for this object is to let the application
configure common display preferences before creating a context, and
there are a few different aspects to this...</p>
<p>Firstly there are options directly relating to the physical display
pipeline that is currently being used including the digital to
analogue conversion hardware and the screens the user sees.</p>
<p>Another aspect is that display options may constrain or affect how
onscreen framebuffers should later be configured. The original
rationale for the display object in fact was to let us handle GLX
and EGLs requirements that framebuffers must be "compatible" with
the config associated with the current context meaning we have to
force the user to describe how they would like to create their
onscreen windows before we can choose a suitable fbconfig and
create a GLContext.</p>

common state of the display pipeline that applies to the whole

<div class="note">Many applications don't need to explicitly use
<a class="link" href="cogl-2.0-experimental-CoglDisplay---Setup-a-display-pipeline.html#cogl-display-new" title="cogl_display_new ()"><code class="function">cogl_display_new()</code></a> and can just jump straight to <a class="link" href="cogl-2.0-experimental-The-Top-Level-Context.html#cogl-context-new" title="cogl_context_new ()"><code class="function">cogl_context_new()</code></a>
and pass a <code class="literal">NULL</code> display argument so Cogl will automatically
connect and setup a renderer and display.</div>
<p>A <em class="parameter"><code>display</code></em>
can only be made for a specific choice of renderer which
is why this takes the <em class="parameter"><code>renderer</code></em>
argument.</p>
<p>A common use for explicitly allocating a display object is to
define a template for allocating onscreen framebuffers which is
what the <em class="parameter"><code>onscreen_template</code></em>
argument is for, or alternatively
you can use <code class="function">cogl_display_set_onscreen_template()</code>.</p>
<p>When a display is first allocated via <a class="link" href="cogl-2.0-experimental-CoglDisplay---Setup-a-display-pipeline.html#cogl-display-new" title="cogl_display_new ()"><code class="function">cogl_display_new()</code></a> it is in a
mutable configuration mode. It's designed this way so we can
extend the apis available for configuring a display without
requiring huge numbers of constructor arguments.</p>
<p>When you have finished configuring a display object you can
optionally call <a class="link" href="cogl-2.0-experimental-CoglDisplay---Setup-a-display-pipeline.html#cogl-display-setup" title="cogl_display_setup ()"><code class="function">cogl_display_setup()</code></a> to explicitly apply the
configuration and check for errors. Alternaitvely you can pass the
display to <a class="link" href="cogl-2.0-experimental-The-Top-Level-Context.html#cogl-context-new" title="cogl_context_new ()"><code class="function">cogl_context_new()</code></a> and Cogl will implicitly apply your
configuration but if there are errors then the application will
abort with a message. For simple applications with no fallback
options then relying on the implicit setup can be fine.</p>

optional since Cogl will internally setup the display if not done

<p>Its possible to request a configuration that might not be

get an opportunity to handle that and the application may abort

fallback options this behaviour may be fine.</p>

<p class="stability">Stability Level: <acronym title="Unstable interfaces are experimental or transitional. They are typically used to
give outside developers early access to new or rapidly changing technology, or
to provide an interim solution to a problem where a more general solution is
anticipated. No claims are made about either source or binary compatibility from
one minor release to the next.
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.
