Relicense Bevy under the dual MIT or Apache-2.0 license (#2509) This relicenses Bevy under the dual MIT or Apache-2.0 license. For rationale, see #2373. * Changes the LICENSE file to describe the dual license. Moved the MIT license to docs/LICENSE-MIT. Added the Apache-2.0 license to docs/LICENSE-APACHE. I opted for this approach over dumping both license files at the root (the more common approach) for a number of reasons: * Github links to the "first" license file (LICENSE-APACHE) in its license links (you can see this in the wgpu and rust-analyzer repos). People clicking these links might erroneously think that the apache license is the only option. Rust and Amethyst both use COPYRIGHT or COPYING files to solve this problem, but this creates more file noise (if you do everything at the root) and the naming feels way less intuitive. * People have a reflex to look for a LICENSE file. By providing a single license file at the root, we make it easy for them to understand our licensing approach. * I like keeping the root clean and noise free * There is precedent for putting the apache and mit license text in sub folders (amethyst) * Removed the `Copyright (c) 2020 Carter Anderson` copyright notice from the MIT license. I don't care about this attribution, it might make license compliance more difficult in some cases, and it didn't properly attribute other contributors. We shoudn't replace it with something like "Copyright (c) 2021 Bevy Contributors" because "Bevy Contributors" is not a legal entity. Instead, we just won't include the copyright line (which has precedent ... Rust also uses this approach). * Updates crates to use the new "MIT OR Apache-2.0" license value * Removes the old legion-transform license file from bevy_transform. bevy_transform has been its own, fully custom implementation for a long time and that license no longer applies. * Added a License section to the main readme * Updated our Bevy Plugin licensing guidelines. As a follow-up we should update the website to properly describe the new license. Closes #2373

Introduce detailed_trace macro, use in TrackedRenderPass (#7639) Profiles show that in extremely hot loops, like the draw loops in the renderer, invoking the trace! macro has noticeable overhead, even if the trace log level is not enabled. Solve this by introduce a 'wrapper' detailed_trace macro around trace, that wraps the trace! log statement in a trivially false if statement unless a cargo feature is enabled # Objective - Eliminate significant overhead observed with trace-level logging in render hot loops, even when trace log level is not enabled. - This is an alternative solution to the one proposed in #7223 ## Solution - Introduce a wrapper around the `trace!` macro called `detailed_trace!`. This macro wraps the `trace!` macro with an if statement that is conditional on a new cargo feature, `detailed_trace`. When the feature is not enabled (the default), then the if statement is trivially false and should be optimized away at compile time. - Convert the observed hot occurrences of trace logging in `TrackedRenderPass` with this new macro. Testing the results of ``` cargo run --profile stress-test --features bevy/trace_tracy --example many_cubes -- spheres ``` ![image](https://user-images.githubusercontent.com/1222141/218298552-38551717-b062-4c64-afdc-a60267ac984d.png) shows significant improvement of the `main_opaque_pass_3d` of the renderer, a median time decrease from 6.0ms to 3.5ms. --- ## Changelog - For performance reasons, some detailed renderer trace logs now require the use of cargo feature `detailed_trace` in addition to setting the log level to `TRACE` in order to be shown. ## Migration Guide - Some detailed bevy trace events now require the use of the cargo feature `detailed_trace` in addition to enabling `TRACE` level logging to view. Should you wish to see these logs, please compile your code with the bevy feature `detailed_trace`. Currently, the only logs that are affected are the renderer logs pertaining to `TrackedRenderPass` functions
