Right-clicking the Effect Controls panel did nothing outside an
effect's header. As in After Effects, a right-click anywhere a control
has no menu of its own (the empty area, property names, buttons such
as Reset) now opens the Effect menu: Effect Controls, Last Effect,
Remove All, Manage Effects and every effect category, applying the
chosen effect to the selected layers. It is the menu bar's own Effect
menu tree and drawing code; an effect header keeps its own menu.
Test: right_click_in_effect_controls_shows_the_effect_menu.
