& Logo centered on record window

[Xarxus]

I've noticed that the official D&D theme shows a very faded "&" logo in the center of the record windows.
I don't believe it's just the simple contentframe that does this, otherwise resizing the window would repeat. The one instead remains centered vertically and horizontally.
Do you have any idea how this was done?

Found! ;)

decal tag in framedef is the solution. This is my code.
<framedef name="recordbackground">
<bitmap file="[MY IMAGE]" />
<decal>0,0,[IMAGE WIDTH],[IMAGE HEIGHT]</decal>
</framedef>
