Lay the Klondike table out the way a real one is

Browse Source 
Three changes, all about where things are and how much room they take.

Columns now overlap by a third rather than sitting one under another. A column
of thirteen took more vertical space than a phone has; overlapped, it fits, and
a third is the most that can be hidden while every card still shows its rank and
suit. Absolute offsets rather than negative spacing, because the column has to
work out its own height anyway to reserve the right room.

The cards turned off the stock fan sideways by the same third. Drawing three and
showing one hid two cards the player is entitled to see -- they are face up on
the table. Only the last is playable, which the rules already enforce; the other
two are there to be read.

The stock and the cards turned from it move to the bottom left, under the hand
that turns them, and the foundations keep the top on their own. That is where
both live on a real table, and it puts the pile you tap most within reach of a
thumb rather than at the far corner of the screen.
