Drop the square panel outlines drawn over the rounded plates

The left, middle and select-bar panels each got a hand-drawn 1px square
outline from the pre-plate layout, painted over plates that now have
rounded corners, so the square corners poked out past the rounded ones.
The plate draws its own (rounded) border when the config sets one.
