- * This class allows access to Android's direct texturing mechanism. Locking
- * the buffer gives you a pointer you can read/write to directly. It is fully
- * threadsafe, but you probably really want to use the AndroidDirectTexture
- * class which will handle double buffering.
- *
- * In order to use the buffer in OpenGL, just call Bind() and it will attach
- * to whatever texture is bound to GL_TEXTURE_2D.
