Detailed Description

RAII-style context save/restore class.

Cairo::Context::save() is called automatically when the object is created, and Cairo::Context::restore() is called when the object is destroyed. This allows you to write code such as:

// context initial state
{
  Cairo::SaveGuard saver(context);
  ... // manipulate context
}
// context is restored to initial state

Since cairomm 1.18:
