Interface to C language function:
void {@native glReadPixels}(GLint x, GLint y, GLsizei width, GLsizei height, GLenum format, GLenum type, GLvoid * pixels);

        final GL gl = GLContext.getCurrentGL();


        final int pixFormat = JoglTextureUtil.getGLPixelFormat(format);
        final int pixDataType = JoglTextureUtil.getGLPixelDataType(type);
        // N.B: it expects depth = 1 & pack = true
        gl.glReadPixels(x, y, w, h, pixFormat, pixDataType, store);
    }


    @Override
    public int getExpectedBufferSizeToGrabScreenContents(final ImageDataFormat format, final PixelDataType type,
            final int w, final int h) {
