Allows the Settings > Hotkeys screen to be localised, including hotkey decriptions, groups and contexts.
The hotkey names are exposed to localisation via KeycodeExts. Hotkey modifiers are similarly exposed via ModifersExts.
The Settings > Input screen has a Zoom Modifier dropdown, which shows the localised modifier name.
The --check-yaml utility command is taught to recognise all hotkey translation, so it can validate their usage.
The Text element of these widgets was changed from display text to a translation key as part of adding translation support. Functions interested in the display text need to invoke GetText instead. Lots of functions have not been updated, resulting in symptoms such as measuring the font size of the translation key rather than the display text and resizing a widget to the wrong size.
Update all callers to use GetText when getting or setting display text. This ensure their existing functionality that was intended to work in terms of the display text and not the translation key works as expected.
- Add prefixes to all message keys to provide context
- Use messages with attributes for some UI elements (dropdowns, dialogs, checkboxes, menus)
- Rename some class fields for consistency with translation keys
