A Rust implementation of [glMatrix](http://glmatrix.net/)

gl_matrix provides utilities or all [glMatrix](http://glmatrix.net/) functions in Rust. 
 
 # Quick Start

 Getting started should be easy if you are already familiar with [glMatrix](http://glmatrix.net/) 
 and Rust. All functions have been re-named to be idiomatic Rust. 
 
 ```rust
 use gl_matrix::common::*;
 use gl_matrix::{vec3, mat4};
 
 let canvas_w = 800_f32; 
 let canvas_h = 600_f32;
  
 let mut world_matrix: Mat4 = [0.; 16];
 let mut view_matrix: Mat4 = [0.; 16];
 let mut proj_matrix: Mat4 = [0.; 16];
 
 let eye = vec3::from_values(0., 0., -8.);
 let center = vec3::from_values(0., 0., 0.); 
 let up = vec3::from_values(0., 1., 0.);
 
 mat4::identity(&mut world_matrix);
 mat4::look_at(&mut view_matrix, &eye, &center, &up);
 mat4::perspective(&mut proj_matrix, to_radian(45.), canvas_w / canvas_h, 0.1, Some(100.0));
```
## Features 
- No std 
- Compiles to wasm 
- Familar syntax

## Future work 
- Add support for f64 (Currently only f32) 
- Add support for forEach
