Solid work. In the future, adding more commits rather than rebasing will make it slightly easier for reviewers to tell what's changed :) |

Objective
Provide an example of how to achieve pixel-perfect "grid snapping" in 2D via rendering to a texture. This is a common use case in retro pixel art game development.
Solution
Render sprites to a canvas via a Camera, then use another (scaled up) Camera to render the resulting canvas to the screen. This example is based on the
3d/render_to_texture.rsexample. Furthermore, this example demonstrates mixing retro-style graphics with high-resolution graphics, as well as pixel-snapped rendering of aMaterialMesh2dBundle.
