-- Caribou layout engine (XML)
-- matchbox-keyboard layout engine (XML)
-- delay initialization of XKB and XKL layouts
-- add eek_keyboard_find_by_position(), that takes account of section
rotation, in addition to eek_container_find_by_position()
-- add mechanism to change appearances (colors?) of UI widgets
depending on modifier states
