Constructors

this this(Region region): Undocumented in source.
this this(cairo_region_t* ptr): Create a Region from a existing cairo_region_t*. Context is a garbage collected class. It will call cairo_region_destroy when it gets collected by the GC or when dispose() is called.
this this(Rectangle!int rect)
this this(Rectangle!int[] rects)

Destructor

~this ~this(): Undocumented in source.

Postblit

this(this) this(this): Constructor that tracks the reference count appropriately. If !refCountedIsInitialized, does nothing.
