b07db8462f Bevy derives handling generics in impl definitions. (#2044)
Fixes #2037 (and then some)

Problem:
- `TypeUuid`, `RenderResource`, and `Bytes` derive macros did not properly handle generic structs. 

Solution:
- Rework the derive macro implementations to handle the generics.

c9b33e15f8 gltf: load textures asynchronously using io task pool (#1767)
While trying to reduce load time of gltf files, I noticed most of the loading time is spent transforming bytes into an actual texture.

This PR add asynchronously loading for them using io task pool in gltf loader. It reduces loading of a large glb file from 15 seconds to 6~8 on my laptop

To allow asynchronous tasks in an asset loader, I added a reference to the task pool from the asset server in the load context, which I can use later in the loader.

85ab55a05b Adds an alias mouse position -> cursor position (#2038)
This alias is to aid people finding the cursor_position function, as the mouse
pressed / moved functionality and naming likely primes people for thinking
of "mouse" before "cursor" when searching the api documentation.

86ad5bf420 Adding WorldQuery for WithBundle (#2024)
In response to #2023, here is a draft for a PR. 

Fixes #2023

I've added an example to show how to use `WithBundle`, and also to test it out. 

Right now there is a bug: If a bundle and a query are "the same", then it doesn't filter out
what it needs to filter out. 

Example: 

```
Print component initated from bundle.
[examples/ecs/query_bundle.rs:57] x = Dummy( <========= This should not get printed
    111,
)
[examples/ecs/query_bundle.rs:57] x = Dummy(
    222,
)
Show all components
[examples/ecs/query_bundle.rs:50] x = Dummy(
    111,
)
[examples/ecs/query_bundle.rs:50] x = Dummy(
    222,
)
```

However, it behaves the right way, if I add one more component to the bundle,
so the query and the bundle doesn't look the same:

```
Print component initated from bundle.
[examples/ecs/query_bundle.rs:57] x = Dummy(
    222,
)
Show all components
[examples/ecs/query_bundle.rs:50] x = Dummy(
    111,
)
[examples/ecs/query_bundle.rs:50] x = Dummy(
    222,
)
```

I hope this helps. I'm definitely up for tinkering with this, and adding anything that I'm asked to add
or change.

cdb9097ed4 Make Command's public? (#2034)
I'm using Bevy ECS in a project of mine and I'd like to do world changes asynchronously. 

The current public API for creating entities, `Commands` , has a lifetime that restricts it from being sent across threads. `CommandQueue` on the other hand is a Vec of commands that can be later ran on a World. 

So far this is all public, but the commands themselves are private API. I know the intented use is with `Commands`, but that's not possible for my use case as I mentioned, and so I simply copied over the code for the commands I need and it works. Obviously, this isn't a nice solution, so I'd like to ask if it's not out of scope to make the commands public?

cf40f4ab08 Fix mesh with no vertex attributes causing panic (#2036)
If a mesh without any vertex attributes is rendered (for example, one that only has indices), bevy will crash since the mesh still creates a vertex buffer even though it's empty. Later code assumes that there is vertex data, causing an index-out-of-bounds panic. This PR fixes the issue by adding a check that there is any vertex data before creating a vertex buffer.

I ran into this issue while rendering a tilemap without any vertex attributes (only indices).

2fcd8a3fb0 Monomorphize various things (#1914)
Based on #1910

This shrinks breakout from 310k to 293k. Most of the win is in outlining the drop glue of `App`. The other two commits save about 800 bytes total when using two empty systems and two simple resources.

After this PR the full disassembly for

```rust
fn main() {
    App::build().run();
}
```

is about as minimal as it gets, so pretty much all other costs scale linear in the amount of resources, systems, etc.

0a8576b710 support assets of any size (#1997)
Fixes #1892 

The following code is a cut down version of the issue, and crashes the same way:
```rust
enum AssetLifecycleEvent <T> {
    Create(T),
    Free
}

fn main() {
    let (sender, _receiver) = crossbeam_channel::unbounded();
    sender.send(AssetLifecycleEvent::<[u32; 32000]>::Free).unwrap();
}
```

- We're creating a channel that need to be able to hold `AssetLifecycleEvent::Create(T)` which has the size of our type `T`
- The two variants of the enums have a very different size

By keeping `T` boxed while sending through the channel, it doesn't crash

I wanted to explore system sets and run criteria a bit, so made an example expanding a bit on the snippets shown in the 0.5 release post.

Shows a couple of system sets, uses system labels, run criterion, and a use of the interesting `RunCriterion::pipe` functionality.

d653ad2bda Updated docs for ShouldRun (#1987)
The documentation for `ShouldRun` doesn't completely explain what each of the variants you can return does. For instance, it isn't very clear that looping systems aren't executed again until after all the systems in a stage have had a chance to run.

This PR adds to the documentation for `ShouldRun`, and hopefully clarifies what is happening during a stage's execution when run criteria are checked and systems are being executed.

1248a639ee EnumVariantMeta derive (#1972)
There are cases where we want an enum variant name. Right now the only way to do that with rust's std is to derive Debug, but this will also print out the variant's fields. This creates the unfortunate situation where we need to manually write out each variant's string name (ex: in #1963), which is both boilerplate-ey and error-prone. Crates such as `strum` exist for this reason, but it includes a lot of code and complexity that we don't need.

This adds a dead-simple `EnumVariantMeta` derive that exposes `enum_variant_index` and `enum_variant_name` functions. This allows us to make cases like #1963 much cleaner (see the second commit). We might also be able to reuse this logic for `bevy_reflect` enum derives.

cbfb456847 [bevy_core/bytes] Fix UB with accessing memory with incorrect alignment (#1966)
After running `bevy_core` through `miri`, errors were reported surrounding incorrect memory accesses within the `bytes` test suit. 

Specifically:
```
test bytes::tests::test_array_round_trip ... error: Undefined Behavior: accessing memory with alignment 1, but alignment 4 is required
   --> crates/bevy_core/src/bytes.rs:55:13
    |
55  |             (*ptr).clone()
    |             ^^^^^^ accessing memory with alignment 1, but alignment 4 is required
    |
```

and 

```
test bytes::tests::test_vec_bytes_round_trip ... error: Undefined Behavior: accessing memory with alignment 2, but alignment 4 is required
   --> /home/nward/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/library/core/src/slice/raw.rs:95:14
    |
95  |     unsafe { &*ptr::slice_from_raw_parts(data, len) }
    |              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ accessing memory with alignment 2, but alignment 4 is required
    |
```

Solution:

The solution is to use `slice::align_to` method to ensure correct alignment.

# Examples

```rust
use std::convert::TryInto;
use bevy_render::mesh::VertexAttributeValues;

// creating vector of values
let before = vec![[0_u32; 4]; 10];
let values = VertexAttributeValues::from(before.clone());
let after: Vec<[u32; 4]> = values.try_into().unwrap();

assert_eq!(before, after);

3d4b1b9ff2 Fix alien_cake_addict: cake should not be at height of player's location (#1954)
Just to avoid confusion to close readers of the example, this fix ensures cake is transformed to the height at the cake's cell, rather than the height at the player's cell.

Without this, cake may be floating or buried, depending on where the player is standing at time of spawning.

Love your work!

4f1689ec37 Added example of entity sorting by components (#1817)
We discussed with @alice-i-cecile privately on iterators and agreed that making a custom ordered iterator over query makes no sense since materialization is required anyway and it's better to reuse existing components or code. Therefore, just adding an example to the documentation as requested.

Fixes #1470.

07cf088f33 fix memory size for PointLightBundle (#1940)
Introduced in #1778, not fixed by #1931 

The size of `Lights` buffer currently is : 
```rust
    16 // (color, `[f32; 4]`)
    + 16 // (number of lights, `f32` encoded as a `[f32; 4]`)
    + 10 // (maximum number of lights)
        * ( 16 // (light position, `[f32; 4]`
          + 16 // (color, `[16; 4]`)
          + 4 // (inverse_range_squared, `f32`)
          )

-> 392
```

This makes the pbr shader crash when running with Xcode debugger or with the WebGL2 backend. They both expect a buffer sized 512. This can also be seen on desktop by adding a second light to a scene with a color, it's position and color will be wrong.

adding a second light to example `load_gltf`:
```rust
    commands
        .spawn_bundle(PointLightBundle {
            transform: Transform::from_xyz(-3.0, 5.0, -3.0),
            point_light: PointLight {
                color: Color::BLUE,
                ..Default::default()
            },
            ..Default::default()
        })
        .insert(Rotates);
```

This PR changes `inverse_range_squared` to be a `[f32; 4]` instead of a `f32` to have the expected alignement

97b26d7647 limit number of lights (#1946)
Fixes #1921 

Buffer was growing with the actual number of lights instead of being limited to the max number of lights.

As it's a query that can be exactly sized, I also switched `count()` to `len()`
