(No version information available, might only be in SVN)

## Introduction

CairoContent 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 CairoContent values distinct from CairoContent values so that the implementation can detect the error if users confuse the two types.

## Class synopsis

CairoContent {
/* Constants */
