* Update GitHub Actions
- actions-rs is unmaintained.
- See: https://github.com/actions-rs/toolchain/issues/216
- Enable rust-cache
- Cargo.lock was removed in #63 but it's necessary for reproducible builds in CI.
- The lock file is ignored by dependents.
- Our separate `pixels-ci-rust-version` repo also ignores it, so CI will still be able to tell us if the crate build ever breaks due to unlocked dependencies.
- See the `rust-version` job in ci.yml.

- This version is different from the MSRV. It specifies the minimum
version required to build the crate and its direct dependencies.
- Add a CI step for building the crate alone with the oldest version
possible.
- See MSRV.md for the policy and minimal version supported by CI,
including all example code.
- Update all actions to checkout/v3
* Fix half-pixel offsets in scaling renderer
- This bug was very subtle. It can be hard to notice!
- Context: When the scaling renderer transformation matrix is created,
it needs to center the image within the border.
- The previous code always evaluated the translation to (0, 0)
- This PR makes half-pixel adjustments to the translation when needed,
making it impossible to rasterize the texture on a half-pixel
boundary.
- I spotted this while working on pixel-aspect-ratio support, but it can
most easily be witnessed in the `conway` example by grabbing the top
or bottom resize handle on the window and slow dragging it up and down
by 1-pixel-at-a-time. When you hit a half-pixel bug the entire texture
will change slightly; some pixels will become hidden or duplicated.
* Bump MSRV
- The dependencies are a mess!
- Had to fork `imgui-wgpu`, which sits between 0.12 and 0.13 (has support for `winit` 0.24, but not `wgpu` 0.7)
- This is a temporary fix for CI, until https://github.com/Yatekii/imgui-wgpu-rs/pull/44 is merged and a new release of `imgui-wgpu` is out
- The WIP `wgpu` 0.7 update in https://github.com/parasyte/pixels/pull/134 will be needed for `imgui-wgpu` 0.14
- Update MSRV for `imgui` 0.7
