Use Fused-Multiply-Add (#232)
- There are a few places in the `simple-invaders` crate that could use
  `f32::mul_add()` as well.

Simplify vertex attributes (#228)
- Vertex UVs can be computed from the positions, which saves a small amount of code and a small amount of bandwidth (both inconsequential).
- This is mostly for readability.
- Fixes vertically-flipped pixel buffer in the `custom-shader` example.

Update to wgpu 0.9 (#179)
* Update to wgpu 0.9

* Fix validation error in WGSL shader

- This moves the hardcoded vertex positions and texture coordinates to
  the vertex buffer.
- Replaces the two-triangle quad to 1 full-screen triangle (fixes #180)
- Rewrites the custom shader example to fix a bug with large surface
  textures;
  - The input texture size was used for the output texture, causing the
    purple rectangle to appear very jumpy on large displays in full screen.
- The `ScalingRenderer` now exposes its clipping rectangle. The custom
  shader example uses this for its own clipping rectangle, but it can
  also be used for interacting with the border in general.

* Switch to `wgpu::include_wgsl!()`

- This is a nice little simplification.
- Thanks to @JMS55 for the suggestion!
