- *
- * NOTE: this module and its submodules are only temporary. It is a copy-paste of the bevy-debug-lines
- *       crate: https://github.com/Toqozz/bevy_debug_lines (MIT license)
- * It has been partially updated to work with bevy 0.7, but hasn’t been released yet.
- * So, in the mean time, we are keeping a version here that we will replace by the
- * upstream dependency once:
- * 1. The version compatible with bevy 0.7 is released to crates.io.
- * 2. We find a way to make the 2D version work with our examples. The problem
- *    only happens when running our own examples because cargo’s unification of
- *    features will enable the `3d` feature of `bevy_debug_lines` when running
- *    a `2d` example.
