If we're fading a view with weston_fade_run() and half way through we
want to unfade it we can use weston_fade_update() to set a new alpha
target. When the animation finishes, reset_alpha() is called which
ensures the alpha value of the view is exactly as requested.
Although weston_fade_update() was updating the spring target so the
animation would look fine, it would then reset to the alpha target
given in the first call to weston_fade_run().
weston_fade_update(struct weston_view_animation *fade, float target)
{
fade->spring.target = target;
+ fade->stop = target;
}
