<strong class="classname">CairoContent</strong> is used to describe the content that a surface will contain,
whether color information, alpha information (translucence vs. opacity), or both.

<p class="para">

<strong class="classname">CairoContent</strong> values so that the implementation can detect the error if users confuse the
two types.
