|
* An interface used to wrap a GL interface.
|
|
* <p>Typically
|
|
* used for implementing debugging and tracing on top of the default
|
|
* GL interface. You would typically use this by creating your own class
|
|
* that implemented all the GL methods by delegating to another GL instance.
|
|
* Then you could add your own behavior before or after calling the
|
|
* delegate. All the GLWrapper would do was instantiate and return the
|
|
* wrapper GL instance:
|
|
* <pre class="prettyprint">
|
|
* class MyGLWrapper implements GLWrapper {
|
|
* GL wrap(GL gl) {
|
|
* return new MyGLImplementation(gl);
|
|
* }
|

* static class MyGLImplementation implements GL,GL10,GL11,... {

* ...
