[bgw-gui] Broken CardStack alignment

[taubenangriff]

Describe the bug

Setting Height/Width on a CardView as well as on a CardStack results in the positioning being off. This is due to card and StackWidth being added.

To Reproduce
Steps to reproduce the behavior:

Set up two card stacks:

val stackLeft = CardStack<CardView>(
        height = 180,
        width = 130,
        posX = width/2 + 100,
        posY = height/2)

val stackRight = CardStack<CardView>(
        height = 0,
        width = 0,
        posX = width/2 + 100,
        posY = height/2)

each with CardViews initialized to height=180, width=130.

Expected behavior

The CardStack should be aligned by using just the individual cards dimension for positioning.

Screenshots / Stack trace
If applicable, add screenshots and/or stack trace to help explain your problem.

As we can see, stackLeft is moved out of position, while stackRight is perfectly centered.
