[WIP] Add vertex buffer creation

This PR adds vertex buffers to surfaces and prepares the egl drawing to the monitor.

- [x] Get the monitor to display EGL things
- [x] Add the vertex buffer to surfaces
- [x] Add a global redraw loop
- [x] Make it work
Maybe we care about the return value here, for logging at least... would like you to add a `@todo logging` here...
