Big symbol text in the background

Recently I heard the suggestion to add a security symbol written in big letters in the chart background. Well, actually it is pretty simple to do using low-level gfx. Just add this code sniplet anywhere in your chart formula.

GfxSetOverlayMode(1);
GfxSelectFont("Tahoma"Status("pxheight")/);
GfxSetTextAlign);// center alignment
GfxSetTextColorColorRGB200200200 ) );
GfxSetBkMode(1); // transparent
GfxTextOutName(), Status("pxwidth")/2Status("pxheight")/12 );

UPDATE: I have added transparent mode, so it works fine on non-white backgrounds too.
