Some examples don't compile

[porky11]

Examples alpha, path, quickstart and polygon don't compile.

They use glutin instead of winit when using the vulkan backend.

Fixed:

• alpha
• path
• quickstart
• polygon

The reason for this is that bufro used to use glow for rendering. When I switched it to wgpu, I lost motivation and I never ended up fixing those examples. I'm not paying much attention to this project anymore (though something better is in the works, also using wgpu). I recommend using femtovg for vector graphics, it's much more complete.

I'm using femtovg for some time already, but I wanted to switch to wgpu anyway.
And now it's even more important, since I want to get into bevy and want to have proper vector graphics.
There is a wgpu port of femtovg, but it doesn't compile.
