Raid frame change depending on Specialization

[Paopao001]

I wanted create two raid frames.One for healers(1) and the other for dps/tank(2).

Differences：
Size
Position
Indicators are only shown on the first one.
Aura icon size
Unit name's position on it's owner
Anchor-point, column Anchor-point(healer:5*5 dps/tank:1*25)

When I switch my spec, I want the raid frame to change with it. (without reload UI)

I've tried to use only one raid frame at first.But if I use oUF:SpawnHeader to a already 'spawned' one, there would be a lua error.However,I didn't know how to apply changes in other way.
Later I created two raid frames, I found the key is to hide one and show the other.I can't find a direct way to hide the raid frame. I finally came up with things below after lots of trial and error.

I did it, but I think my code probably is not the best solution.
I even doubt it may has some unknown side effects.
Anyone knows an easier way to do this?

Here's my code and add-on.

There is a macro conditional for specs.

You could have 2 raidframes and add a macro condition via RegisterStateDriver to each of them.

--frame1
local frame1 = CreateFrame("FRAME","MyRaidDragFrameForDPS",UIParent, "SecureHandlerStateTemplate")
RegisterStateDriver(frame1, "visibility", "[spec:1] show;hide")
--frame2
local frame2 = CreateFrame("FRAME","MyRaidDragFrameForHEAL",UIParent, "SecureHandlerStateTemplate")
RegisterStateDriver(frame2, "visibility", "[spec:2] show;hide")

But I'm not sure if that is will kill all the performance heavy events in the background. Since the frame that all the headers should be anchored to is hidden it should work out.
