Bevy 0.7

[Shatur]

This PR contains two changes (separate commits) related to Bevy:

• Previously used render feature is a group that contains unneeded stuff, like bevy_ui or bevy_text. Specified features in this PR is the required minimum. You can read more about in in this issue: Feature render depends on bevy_ui bevyengine/bevy#4202
• Update to Bevy 0.7. All changes comes from this PR in Bevy, which I used to get information about what changed. But currently it crashes with the following error:

thread 'main' panicked at 'range end index 176 out of range for slice of length 160', .cargo/registry/src/github.com-1ecc6299db9ec823/bevy_render-0.7.0/src/mesh/mesh/mod.rs:241:17

So the PR is draft.

Is the crash an issue upstream with bevy or were you just unable to figure out the cause of it in bevy_debug_lines?

Also what example are you running to get the crash? I can't seem to reproduce.

I think that the crash is caused by bevy_debug_lines.

Also what example are you running to get the crash? I can't seem to reproduce.

I running cargo run --example 3d --features="example_deps"

any progress here?

[Shatur]

It crashes, we don't know how to solve it currently.

First crash is because bevy switched to u32's for mesh colors, which is a hassle but not too hard to fix.

Second issue is that bevy changed seems to require normals, uvs, and probably indices for custom meshes now, at least when using the SpecializedMeshPipeline, all of which would be pointless for us to provide since they aren't used.
I think the solution is probably going to have to be to switch to SpecializedRenderPipeline, but its a fair bit to figure out and I'm busy until the weekend

I'm considering just raising an issue with bevy to not require those properties on meshes that don't need it.

P.S: Could be wrong, maybe there's a flag I can set.

[Toqozz]

Fix acquired, will push tomorrow-ish.

Thanks @superdump!

Sorry for the delay. Bevy 0.7 should work with master. I feel like the colors may still be off but I'm not sure.

I'll push a crate update in a few days once we see if any issues arise.

Also, thank you for the pull request! I pulled the relevant changes in but not through GitHub, so I'll close this now. Feel free to comment though.

Thanks again!
