Add fullscreen button to examples
Sometimes, especially on smaller screens, it can be useful to Fullscreen an example to view it properly. This PR adds a simple Fullscreen button to the examples.
I've deliberately decided against making it hover over the example in a corner, as that would cover parts of the example and potentially interfere with UI placed in the same location.
I've made the icon myself, using https://graphite.rs. Should I also add the project file, as it allows parametric control to adjust the icon?
I think we can omit the project file
Fair enough. I mostly used the chance to play around with graphite.rs - very cool, if a few rough corners.
Oh and a third thing that just crossed my mind, we should have the cursor be a pointer over the button to enter full screen. https://developer.mozilla.org/en-US/docs/Web/CSS/cursor
