<p class="description">
Creates a shader program given the GLSL source for a vertex and fragment shader.
<br /><br />
The vertex and fragment shader are individually compiled, and then linked together
to create a shader program. An exception is thrown if any errors are encountered,
as described below.
<br /><br />
The program's active uniforms and attributes are queried and can be accessed using
the returned shader program. The caller can explicitly define the vertex
attribute indices using the optional <code>attributeLocations</code> argument as
shown in example two below.

<p class="description">
Creates a vertex array from a mesh. A mesh contains vertex attributes and optional index data
in system memory, whereas a vertex array contains vertex buffers and an optional index buffer in WebGL
memory for use with rendering.
<br /><br />
The <code>mesh</code> argument should use the standard layout like the mesh returned by <a href="BoxTessellator.html">BoxTessellator</a>.
<br /><br />
<code>creationArguments</code> can have four properties:
<ul>
<li><code>mesh</code>: The source mesh containing data used to create the vertex array.</li>
<li><code>attributeIndices</code>: An object that maps mesh attribute names to vertex shader attribute indices.</li>
<li><code>bufferUsage</code>: The expected usage pattern of the vertex array's buffers. On some WebGL implementations, this can significantly affect performance. See <a href="BufferUsage.html">BufferUsage</a>. Default: <code>BufferUsage.DYNAMIC_DRAW</code>.</li>
<li><code>vertexLayout</code>: Determines if all attributes are interleaved in a single vertex buffer or if each attribute is stored in a separate vertex buffer. Default: <code>VertexLayout.SEPARATE</code>.</li>
</ul>
<br />
If <code>creationArguments</code> is not specified or the <code>mesh</code> contains no data, the returned vertex array is empty.
