iPhone and iPad stop crashing past the title screen

On iPhone and iPad, tapping past the title screen could crash the app on the spot, before you ever reached the game. The hero portraits were trying to draw themselves before they'd been given any space on screen, and drawing into nothing was enough to take the whole app down.

Now those portraits hold off until they actually have room to appear, so leaving the title screen lands you in the game instead of a crash. This was an iOS-only problem; the web and Android builds were already fine.
