I have my own absorbbar module. That's why.

Module
http://code.google.com/p/rothui/sour...otalAbsorb.lua

Create Function

--total absorb
  func.totalAbsorb = function(self)
    if not self.cfg.totalabsorb or (self.cfg.totalabsorb and not self.cfg.totalabsorb.show) then return end
    local w = self.Health:GetWidth()
    if w == 0 then
      w = self:GetWidth()-24.5-24.5 --raids and party have no width on the health frame for whatever reason, thus use self and subtract the setpoint values
    end
    local absorbBar = CreateFrame("StatusBar", nil, self.Health)
    --new anchorpoint, absorb will now overlay the healthbar from right to left
    absorbBar:SetFrameLevel(self.Health:GetFrameLevel()+1)
    absorbBar:SetPoint("TOPRIGHT", self.Health, 0, 0)
    absorbBar:SetPoint("BOTTOMRIGHT", self.Health, 0, 0)
    absorbBar:SetWidth(w)
    absorbBar:SetStatusBarTexture(self.cfg.totalabsorb.texture)
    absorbBar:SetStatusBarColor(self.cfg.totalabsorb.color.bar.r,self.cfg.totalabsorb.color.bar.g,self.cfg.totalabsorb.color.bar.b,self.cfg.totalabsorb.color.bar.a)    
    absorbBar:SetReverseFill(true)
    -- Register with oUF
    self.TotalAbsorb = absorbBar    
  end

Result:


Basically I overlay the healthbar with the absorb bar from right-to-left. The healprediction is underneath.

That way when loosing health I can easily see how much of the health lost is covered by a shield. My shield display caps at maxhealth.

I see no point in adding absorb bar to the healprediction display. Healprediction fills up health that is lost. Absorbbar shows how much of your health is covered by a shield.

My orb uses the same module, just a different create function.

Sidenote I really would have loved to not using a fake statusbar on my orb. The problem is that when setting bar:SetOrientation("VERTICAL") bar:SetReverseFill(true) The statusbar texture crop is wrong. At least for what I'm needing. It will look like the texture is moving in from the top, not filling top-to-bottom. I tried to hook the SetTexCoord function call on the statusbar texture to swap some values but it does not fire :/ Funny enough before applying the Smooth module I tried changing the SetTexCoord via the PostUpdate function but when PostUpdate was called (after SetValue) the SetTexCoord on the statusbar texture had not yet been applied. GetTexCoord() always delivered the old value, never the new one. Wierd!
