This example draws a triangle to the screen using the WebGL API.

## `Cargo.toml`

The `Cargo.toml` enables features necessary to obtain and use a WebGL
rendering context.

```toml
{{#include ../../../examples/webgl/Cargo.toml}}
```

## `src/lib.rs`

This source file handles all of the necessary logic to obtain a rendering
context, compile shaders, fill a buffer with vertex coordinates, and draw a
triangle to the screen.

```rust
{{#include ../../../examples/webgl/src/lib.rs}}
```
