Add/Remove Ambient Sound to/from a Region

[MN Lahmar]

Hi guys, how to Add and Remove Ambient Sound to and from a Region?
(Leak-free please)

Here is a thought:
1. store the region size and position into variables. (this is possible with jass, I am not 100% sure if there is such a function in GUI)
2. destory the region
3. create a new region with triggers based on the variables stored earlier. (this requires jass, it's a fact)

function SetStackedSoundBJ takes boolean add, sound soundHandle, rect r returns nothing
    local real width = GetRectMaxX(r) - GetRectMinX(r)
    local real height = GetRectMaxY(r) - GetRectMinY(r)

    call SetSoundPosition(soundHandle, GetRectCenterX(r), GetRectCenterY(r), 0)
    if add then
        call RegisterStackedSound(soundHandle, true, width, height)
    else
        call UnregisterStackedSound(soundHandle, true, width, height)
    endif
endfunction
