-	// src/mesh.js
-	// Represents indexed triangle geometry with arbitrary additional attributes.
-	// You need a shader to draw a mesh; meshes can't draw themselves.
-	//
-	// A mesh is a collection of `GL.Buffer` objects which are either vertex buffers
-	// (holding per-vertex attributes) or index buffers (holding the order in which
-	// vertices are rendered). By default, a mesh has a position vertex buffer called
-	// `vertices` and a triangle index buffer called `triangles`. New buffers can be
-	// added using `addVertexBuffer()` and `addIndexBuffer()`. Two strings are
-	// required when adding a new vertex buffer, the name of the data array on the
-	// mesh instance and the name of the GLSL attribute in the vertex shader.
-	//
-	// Example usage:
-	//
-	//     var mesh = new GL.Mesh({ coords: true, lines: true });
-	//
-	//     // Default attribute "vertices", available as "gl_Vertex" in
-	//     // the vertex shader
-	//     mesh.vertices = [[0, 0, 0], [1, 0, 0], [0, 1, 0], [1, 1, 0]];
-	//
-	//     // Optional attribute "coords" enabled in constructor,
-	//     // available as "gl_TexCoord" in the vertex shader
-	//     mesh.coords = [[0, 0], [1, 0], [0, 1], [1, 1]];
