GFX Tutorial, part II

Description

Another quick prototype release.

Aside from going through the paces of the GFX tutorial, this release also adds
an experimental embedded game loop library to further learn about the concepts
related to decoupled rendering, and a fixed time step.

It doesn't do anything useful yet, aside from being a well-documented training
ground.

Changes

Game Features

• add initial game loop implementation 07ebc32

  This adds a simple (but well-documented) "game loop" library to the project.

  It's mainly meant for learning purposes, and to see what should, and shouldn't
  be abstracted away in a library.

• "Learn gfx-hal" chapter 4 d4c4880

  This implements the fourth chapter of the "Learn gfx-hal"
  tutorial0.

  Some take-aways:

  • Still same feeling as before, lots of boilerplate code, lots of unsafe
    code. But, having fun going through the courses.

  • Updating the code to use gfx-hal 0.2, contributing the changes back
    upstream1.

  • Also ordered a book2, and started reading a free online
    book3 to brush up on the required knowledge.
