avm1_unload_movie has been adapted to only enter the unloaded state with
one frame delay if the MovieClip is a root MovieClip. The unloaded state
is now immediately entered for non-root MovieClips.
This fixes the regressions #12254 and #12265 which got introduced
because of this delay.
However, in Flash Player, even non-root MovieClips enter the unloaded
state one frame after the unloadMovie command has been read. Ruffle is
probably replacing a MovieClip differently to Flash, therefore
introducing these regressions when trying to emulate that delay.
Documentation explaining this all has been added to avm1_unload_movie.
Therefore, the test movieclip_library_state_values has been added. It
tests the default state and the unloaded state of a (non-root) child
MovieClip that's loaded from the library. It is marked as known_failure
because Ruffle currently doesn't implement the delay before entering the
unloaded state for non-root MovieClips.
The method MovieClip::replace_with_movie accepts an
Option<Arc<SwfMovie>>. If no movie is given, an empty stub movie is
generated and used.
Previously, the IS_ROOT flag has been set for the new replaced SwfMovie,
depending on whether a movie was given to the method or not.
However, there are cases where an explicitely given movie should not be
set as a root movie (e.g. if a specific empty stub movie is given to the
method). Conversely, there are also cases where no movie is given, but
the stub movie should still be set as a root movie (e.g. in specific
MovieClip states).
Therefore, an is_root parameter has been added to the method. This
explicit parameter is now used to set the flag for the new replaced
SwfMovie.
All calls of replace_with_movie have been adapted to use the new
parameter correctly.
Previously, a MovieUnloader has been kept in the LoadManager, even after
the movie has been unloaded.
This has been fixed. A remove_loader method has been added to the
LoadManager. It is now called in the avm1_unload_movie method; every
MovieUnloader will be removed after the unloaded state has been entered.
The documentation about loaders has been improved and fixed in multiple
places, clarifying how loaders are removed.
