# verify-win32-input.sh - Typed-character acceptance gate for the Win32 port.
# Runs KEYS.EXE under Wine (scripts/lib/wineGate.sh) at one window pixel per
# stage pixel (JOEYLIB_SCALE=1, JOEYLIB_ASPECT=square), types the RetroNet
# definition-of-done string with xdotool (real X key events through XTEST,
# which Wine turns into WM_KEYDOWN/WM_CHAR), grabs the window, and decodes
# the example's verification scanline (row 198) with scripts/lib/keysRow.py.
# Then the named keys a second key gives (scripts/lib/keysGate.sh): the
# keypad's arrows and Enter, and the right Ctrl and Alt (the key messages'
# extended bit), read off KEYS's cells (scripts/lib/keysCells.py).
#
# Usage: scripts/verify-win32-input.sh
# Requires: Wine (install.sh install emulator:win32), Xvfb, xdotool,
# ImageMagick, python3 + PIL; build/win32/bin/KEYS.EXE
# (make win32).
