The menu bar's own menus (Edit has 30 entries) had no scroll area, only their submenus did, so
on a short screen Edit ran past the bottom of the window. The font menu was capped at 420
points and never moved up, the Preview panel's and the viewer's popup lists neither scrolled nor
moved, and the Timeline's Blending Mode and Expression Language submenus didn't scroll. egui's
scroll bars also only appeared while the pointer was over the list, so a list could only be
scrolled with a wheel or touchpad.
- widgets::popup_list: the one popup list behind popup_menu, the font menu, the Preview panel's
dropdowns and the viewer's popups: as tall as the window allows, scrolling beyond, moved up to
fit the window.
- widgets::menu_scroll: the same for menus and submenus (the menu bar's, Blending Mode, the
Expression Language menu, the viewer's Select menu).
- Scroll bars always show (solid scroll style), so they can be dragged.
- A first window that doesn't fit the screen is maximized: the 1680 x 1020 default on a smaller
screen is only shrunk to the monitor's size, so with its title bar it ran under the taskbar and
cut menus off at the bottom of the screen even when they fitted the window.
Test: ui_scrolling a_menu_taller_than_the_window_scrolls (Edit in a 520-point window scrolls
its last entry into view and it takes the click); overflows_screen unit test.
