Animation Anchoring

[Crepusculu]

I'm having trouble figuring how to properly anchor my animations, and I need some help.

I built a "fade out" animation that shrinks and fades my custom frames. As the animation runs, each child texture will scale-down towards it's own center instead of its parent frame. How do I get all the textures to scale as an unified unit? Would I have to run a separate "Translation" animation for each texture?

Sample of code I'm running

	local plate = CreateFrame("Frame",nil,UIParent)
	local backleft,backright,backtop,backbottom = plate:CreateTexture(),plate:CreateTexture(),plate:CreateTexture(),plate:CreateTexture()
	backleft:SetTexture(0,0,0)
	backright:SetTexture(0,0,0)
	backtop:SetTexture(0,0,0)
	backbottom:SetTexture(0,0,0)
	
	backtop:SetPoint("TOPLEFT",plate,"TOPLEFT")
	backtop:SetPoint("BOTTOMRIGHT",plate,"TOPRIGHT",0,-2)
	backbottom:SetPoint("BOTTOMLEFT",plate,"BOTTOMLEFT")
	backbottom:SetPoint("TOPRIGHT",plate,"BOTTOMRIGHT",0,2)
	backleft:SetPoint("TOPLEFT",plate,"TOPLEFT")
	backleft:SetPoint("BOTTOMRIGHT",plate,"BOTTOMLEFT",2,0)
	backright:SetPoint("TOPRIGHT",plate,"TOPRIGHT")
	backright:SetPoint("BOTTOMLEFT",plate,"BOTTOMRIGHT",-2,0)
	
	local ag = plate:CreateAnimationGroup()
	ag:SetLooping("NONE")
	ag:SetScript("OnFinished",removePlate)

	local a1 = ag:CreateAnimation("Scale")
	a1:SetScale(-0.33, -0.33)
	a1:SetDuration(1)
	a1:SetSmoothing("IN")
	a1:SetOrigin("CENTER",0,0)
	local a2 = ag:CreateAnimation("Alpha")
	a2:SetChange(-1)
	a2:SetDuration(1)
	a2:SetSmoothing("IN")

	plate:SetAllPoints(realframe)

I can't help you with this. But I can say that the animation stuff is full of bugs. I've tried to build some animations myself and gave up after several days of testing.
Animated fontstrings for example are always scaling to the bottom left corner - regardles of any anchorpoints, parent frames or SetOrigins.
