title: Library to that allows setting of individual pixels within a window
body: <p>I am running Linux. I am looking for a library that will allow me to set up individual pixels within a window on screen. I am working on an embedded application and it would be a lot easier to develop my algorithms on the computer rather than the project. Im looking for something along the lines of <code>display.setPixel(x, y)</code>. Does anybody know of any similar solutions? Im looking for something using C or C++</p>
