elm_transit - Combined effects and options.
This example shows how to apply the following transition effects:
- translation
- color
- rotation
- wipe
- zoom
- resizing
It allows you to apply more than one effect at once, and also allows to set properties like event_enabled, auto_reverse, repeat_times and tween_mode.
