cairo_device_type_t is used to describe the type of a given device. The devices types are also known as "backends" within cairo.
The device type can be queried with cairo_device_get_type()
The various cairo_device_t functions can be used with surfaces of any type, but some backends also provide type-specific functions that must only be called with a device of the appropriate type. These functions have names that begin with cairo_type_device<...> such as cairo_xcb_device_debug_set_render_version().
The behavior of calling a type-specific function with a surface of the wrong type is undefined.
New entries may be added in future versions.
