CairoPatternType is used to describe the type of a given pattern.
The type of a pattern is determined by the function used to create it.
The cairo_pattern_create_rgb() and cairo_pattern_create_rgba()
functions create CairoPatternType::SOLID patterns. The remaining
cairo_pattern_create_* functions map to pattern types in obvious ways.
CairoPatternType::SOLIDThe pattern is a solid (uniform) color. It may be opaque or translucent.
CairoPatternType::SURFACEThe pattern is a based on a surface (an image).
CairoPatternType::LINEARThe pattern is a linear gradient.
CairoPatternType::RADIALThe pattern is a radial gradient.
