    WVR_GenOverlay(&mOverlayId);
    GLuint textureId = 0;
    glGenTextures(1, &textureId);
    glBindTexture(GL_TEXTURE_2D, textureId);
    ...
    glBindTexture(GL_TEXTURE_2D, 0);
    const WVR_OverlayTexture_t texture = { textureId, textureWidth,
                                          textureHeight };
