You can see in the `demo.nim` how to make real time apps with pixie: <https://github.com/treeform/pixie/blob/master/src/pixie/demo.nim>
It just has a pixie image called screen and it transfers it to a texture every frame. It uses GLFW for windowing and input. Here are examples of where demo is used: <https://github.com/treeform/bumpy/blob/master/examples/convexhull.nim> <https://github.com/treeform/bumpy/blob/master/examples/circle2circle.nim> I should probably include a real-time example. I use `staticglfw` because I maintain it: <https://github.com/treeform/staticglfw>
