title: What (minimal) C graphics library provides these functions
body: <p>I have to replace the nano-X stuff in our linux embedded application and need some replacements for the drawing functions <code>Arc, Rect, FillRect, Ellipse, FillEllipse, Line, Text, DrawImageFromFile</code>. </p>
  
  <p>Does anyone know of a suitable open source library that I can use to replace these? Ideally it should work with a pixel buffer in 16bit color, so that writing to the linux framebuffer device is possible.</p>
  
  <p>I thought about <code>libcairo</code> but that is a rather big package fro just this purpose. The use of Qt 4.7 is planned for the future and I'm sure it contains the necessary drawing functions. Should I go directly with that?</p>
