This is my implementation of an oUF element that shows Vengeance for tanks.

Example of usage: Add oUF_SVengeance to your layout's optdeps:

## OptionalDeps: oUF_SVengeance

Add the bar to your player frame in your layout, ex:

    if IsAddOnLoaded("oUF_SVengeance") then
     local v = CreateFrame("statusbar", nil, self)
     v:SetHeight(myheight)
     v:SetWidth(mywidth)
     v:SetPoint(...)
     v.Usetext = true
     self.Vengeance = v
    end

Using this code above you'll create a simple status bar, that fills from left to right. On this element will be automatically placed a fontstring in its middle to show the vengeance value as ex: 4.5k / 16.80k

Options list (you can find this on top in the main lua file.)

Options:
Vengeange:SetStatusBarTexture
	Set a Statusbar texture, default will be used if none specified
Vengeance.Value
	Fontstring, default will be created if none specified. Requires Usetext to not be false.

Vengeance.Usetext = [true | "perc" | false]
	true = shows the amount of vengeance on the bar as ex: 850 / 16.20k if <1000 otherwise will show ex: 1.3k / 16.20k
	"perc" = shows the Value as a % of the max venge, implies true.
	false = doesn't show any text

Vengeance.Orientation = ["VERTICAL" | "HORIZONTAL"]
	by default is HORIZONTAL, meaning left to right.
	Set to "VERTICAL" to have a bar that fills from bottom to top

Vengeance.TextOverride = function(self, curvengeance)
	Can be used to override the default text, requires Vengeance.Usetext to not be false
	curvengeance is the venge you have, ex: 1200
	Vengence.max can be used to retrieve the max venge you can aquire
	Use Vengeance.Value:SetText() to set the text.

Vengeance.PostUpdate = function(self,curvengeance)
	Can be used for further customization, if no function is provided the bar will be colored red if at low venge Value, green at high Venge Value

Note: On the Baleroc encounter the max value will go thru the roof 'couse of the Blaze of Glory buff, I know; btw it's an isolate issue and I don't feel like adding code just to hadle that encounter.

If you find any bug or have suggestions, please send a comment.
