title: What is a graphic context? (iOS)
body: <p>What exactly is a graphic context? When drawing with Core Graphic we get a reference to the context. When I look at the documentation it seems like it is an object or so that take care of the correct drawing whether it is for printing, device, pdf and so on.</p>
  
  <p>Could anyone help me to understand what a context really is? I tried reading the documentation but I do not understand. Is it an object that contains information(meta-data) about a system or something?</p>
  
  <p>Thanks in advance</p>
