-- #781: Linux launcher mouse-dead behind the pad cursor.  Reproduces the
-- X11 multi-monitor failure mode (polled love.mouse.getPosition frozen on
-- desktop-virtual coords, so the motion yield in _updatePadCursor never
-- fires) and asserts a host-forwarded mousepressed reclaims the pointer.
-- Self-contained: `luajit tests/rom_importer_cursor_bug781_test.lua`.
-- Should eventually merge into tests/rom_importer_cursor_test.lua (dofile'd
-- by tests/run_tests.lua).
