The fact that they weren't identical was the source of a bug that was only discovered during the testing of [JDK-8090547](https://bugs.openjdk.java.net/browse/JDK-8090547) on the es2 pipeline.

As a note, I made the `context` field in the `D3DGraphics` final, which it should have been. This is necessary to ensure that moving the method to the super-class is equivalent.

The warning is on the `import` of the class, which can be suppressed by adding the annotation to the class declaration. Maybe it's only this way in the Eclipse compiler.

The question is if this can cause any bugs? Is the method supposed to override? If yes and it isn't, it sounds like something could go wrong.
