"""The iOS quit prompt (dm/ios/Sources/quit_prompt.h), built and run on the Mac.

quit_prompt/quit_prompt_check.m runs the touch steps of the quit state machine (a tap on the quit control opens the prompt, Cancel or a
tap outside closes it, Quit is final, a controller button already held when it opens does not count), and lays the prompt out on the
iPhone, iPad and iPhone Duo screens in the six languages of the launchers: the card stays on the screen, the two pills keep one fixed
width whatever the language and every label fits at full size, and a tap lands where it should. Core Animation and Core Text only, so
no simulator is needed. QP_CAPTURE_DIR=<dir> also draws the prompt to PNGs.
