/**
* <a href="http://www.opengl.org/sdk/docs/man/html/glBufferData.xhtml">OpenGL SDK Reference</a>
* Creates and initializes a buffer object's data store.
*
* <p>{@code usage} is a hint to the GL implementation as to how a buffer object's data store will
* be accessed. This enables the GL implementation to make more intelligent decisions that may
* significantly impact buffer object performance. It does not, however, constrain the actual
* usage of the data store. {@code usage} can be broken down into two parts: first, the frequency
* of access (modification and usage), and second, the nature of that access. The frequency of
* access may be one of these:
*
* <ul>
* <li><em>STREAM</em> - The data store contents will be modified once and used at most a few
* times.
* <li><em>STATIC</em> - The data store contents will be modified once and used many times.
* <li><em>DYNAMIC</em> - The data store contents will be modified repeatedly and used many
* times.
* </ul>
*
* The nature of access may be one of these:
*
* <ul>
* <li><em>DRAW</em> - The data store contents are modified by the application, and used as the
* source for GL drawing and image specification commands.
* <li><em>READ</em> - The data store contents are modified by reading data from the GL, and
* used to return that data when queried by the application.
* <li><em>COPY</em> - The data store contents are modified by reading data from the GL, and
* used as the source for GL drawing and image specification commands.
* </ul>
