Transform:Plane() and Plane functions

[macklebee]

Transform Plane's lua example in the documentation causes an error and fails the program due to the transformed plane returning as nil. I assume its related to also the inability to use the Plane functions in lua as there is no way to define a plane.

This code:

--Create a window
window = Window:Create()
context = Context:Create(window)
world = World:Create()
local camera = Camera:Create() 
camera:Move(0,0,-3) 
local light = DirectionalLight:Create() 
light:SetRotation(35,35,0) 
        
--Create a model
model = Model:Box() 
model:SetColor(0.0,0.0,1.0) 
model:SetPosition(3,0,0)

while true do        
        if window:Closed() or window:KeyHit(Key.Escape) then return false end

        Time:Update()
        world:Update()
        world:Render()

        --We're going to transform the plane (1,0,0,0) from global space to the model's local space
        --Because the model is positioned at (3,0,0) the plane will be at (1,0,0,3) in local space (relative to the model).
        local p = Transform:Plane(1,0,0,0,nil,model)

        context:SetBlendMode(Blend.Alpha) 
        context:DrawText(p:ToString(),2,2) 
        context:SetBlendMode(Blend.Solid) 

        context:Sync()

end

will error with "attempt to call method 'ToString' (a nil value)" implying the tranformed plane was not returned.

The function is working fine but the Plane class has some oddities...fixing now.
