Update vendored Crevice to 0.8.0 + PR for arrays (#3059)
# Objective - Update vendor crevice to have the latest update from crevice 0.8.0 - Using https://github.com/ElectronicRU/crevice/tree/arrays which has the changes to make arrays work ## Solution - Also updated glam and hexasphere to only have one version of glam - From the original PR, using crevice to write GLSL code containing arrays would probably not work but it's not something used by Bevy

|

Crevice is similar to [`glsl-layout`][glsl-layout], but supports types from many
|
||||
math crates, can generate GLSL source from structs, and explicitly initializes
|
||||
padding to remove one source of undefined behavior.
|
||||
|
||||
Examples in this crate use cgmath, but any math crate that works with the mint
|
||||
crate will also work. Some other crates include nalgebra, ultraviolet, glam, and
|
||||
vek.
|
||||
Crevice has support for many Rust math libraries via feature flags, and most
|
||||
other math libraries by use of the mint crate. Crevice currently supports:
|
||||
|
||||
* mint 0.5, enabled by default
|
||||
* cgmath 0.18, using the `cgmath` feature
|
||||
* nalgebra 0.29, using the `nalgebra` feature
|
||||
* glam 0.19, using the `glam` feature
|
||||
|
||||
PRs are welcome to add or update math libraries to Crevice.
|
||||
|
||||
If your math library is not supported, it's possible to define structs using the
|
||||
types from mint and convert your math library's types into mint types. This is
|
||||
supported by most Rust math libraries.
|
||||
|
||||
Your math library may require you to turn on a feature flag to get mint support.
|
||||
For example, cgmath requires the "mint" feature to be enabled to allow
|
||||
conversions to and from mint types.

### Minimum Supported Rust Version (MSRV)
|
||||
## Features
|
||||
|
||||
Crevice supports Rust 1.46.0 and newer due to use of new `const fn` features.
|
||||
* `std` (default): Enables [`std::io::Write`]-based structs.
|
||||
* `cgmath`: Enables support for types from cgmath.
|
||||
* `nalgebra`: Enables support for types from nalgebra.
|
||||
* `glam`: Enables support for types from glam.
|
||||
|
||||
## Minimum Supported Rust Version (MSRV)
|
||||
|
||||
Crevice supports Rust 1.52.1 and newer due to use of new `const fn` features.

|

Crevice is similar to [`glsl-layout`][glsl-layout], but supports types from many
|
||||
math crates, can generate GLSL source from structs, and explicitly initializes
|
||||
padding to remove one source of undefined behavior.
|
||||
|
||||
Examples in this crate use cgmath, but any math crate that works with the mint
|
||||
crate will also work. Some other crates include nalgebra, ultraviolet, glam, and
|
||||
vek.
|
||||
Crevice has support for many Rust math libraries via feature flags, and most
|
||||
other math libraries by use of the mint crate. Crevice currently supports:
|
||||
|
||||
* mint 0.5, enabled by default
|
||||
* cgmath 0.18, using the `cgmath` feature
|
||||
* nalgebra 0.29, using the `nalgebra` feature
|
||||
* glam 0.19, using the `glam` feature
|
||||
|
||||
PRs are welcome to add or update math libraries to Crevice.
|
||||
|
||||
If your math library is not supported, it's possible to define structs using the
|
||||
types from mint and convert your math library's types into mint types. This is
|
||||
supported by most Rust math libraries.
|
||||
|
||||
Your math library may require you to turn on a feature flag to get mint support.
|
||||
For example, cgmath requires the "mint" feature to be enabled to allow
|
||||
conversions to and from mint types.
|
||||
|
||||
