void setupResolutionPolicy(float designW, float designH)
{
 Size screenSize = EGLView::getInstance()->getFrameSize();

 float designRatio = designW / designH;
 float screenRatio = screenSize.height / screenSize.width;

 ResolutionPolicy::FIXED_HEIGHT : ResolutionPolicy::FIXED_WIDTH;

 EGLView::getInstance()->setDesignResolutionSize(designW, designH, resolutionPolicy);
