#cairo_content_t is used to describe the content that a surface will
contain, whether color information, alpha information (translucence
vs. opacity), or both.
Note: The large values here are designed to keep #cairo_content_t
values distinct from #cairo_format_t values so that the
implementation can detect the error if users confuse the two types.
