Renders a 2D text overlay on top of an existing 3D scene. The example implements a text overlay class with separate descriptor sets, layouts, pipelines and render pass to detach it from the rendering of the scene. The font is generated by loading glyph data from a [stb font file](http://nothings.org/stb/font/) into a buffer that's copied to the font image.
After rendering the scene, the second render pass of the text overlay class loads the contents of the first render pass and displays text on top of it using blending.
