Cairo::Content
Inherits Enum / Comparable / Value / Object
Content 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 content values distinct
from Format values so that the implementation can detect the error if users confuse the two types.
