If you use a `Loader` to load an SWF containing a class that shadows an already-defined class, the class definition from the Loader SWF will be ignoredin favor of the already-defined class. This commit applies this log to symbol classes as well - the symbol registry for the class should continue to point to the existing MovieClip in the parent. This results in the child SWF instantiating the class from the parent SWF when the child places the affected movie clip on the timeline. This fixes a bug in Fancy Pants World 4 Part 3, where the sub-level SWF was replacing the symbol class entry for the parent 'shipInteract' class with the dummy clip provided in the sub-level SWF (instead of continuing to use the correct clip from the parent SWF). |

SWF Regression Tests
Inside tests/swfs is a large collection of automated tests that are based around running a swf and seeing what happens.
To create a test, make a directory that looks like the following, at minimum:
- directory/
- test.swf
- test.toml
- output.txt
As best practice, please also include any source used to make the swf - such as test.fla and any actionscript files.
Test Structure
test.toml
Except for num_frames, every other field and section is optional.
num_frames = 1 # The amount of frames of the swf to run
sleep_to_meet_frame_rate = false # If true, slow the tick rate to match the movies requested fps rate
ignore = false # If true, ignore this test. Please comment why, ideally link to an issue, so we know what's up
output_path = "output.txt" # Path (relative to the directory containing test.toml) to the expected output
# Sometimes floating point math doesn't exactly 100% match between flash and rust.
# If you encounter this in a test, the following section will change the output testing from "exact" to "approximate"
# (when it comes to floating point numbers, at least.)
[approximations]
number_patterns = [] # A list of regex patterns with capture groups to additionally treat as approximate numbers
epsilon = 0.0 # The upper bound of any rounding errors. Default is the difference between 1.0 and the next largest representable number
max_relative = 0.0 # The default relative tolerance for testing values that are far-apart. Default is the difference between 1.0 and the next largest representable number
# Options for the player used to run this swf
[player_options]
max_execution_duration = { secs = 15, nanos = 0} # How long can actionscript execute for before being forcefully stopped
viewport_dimensions = { width = 100, height = 100, scale_factor = 1 } # The size of the player. Defaults to the swfs stage size
with_renderer = { optional = false, sample_count = 4, exclude_warp = false } # If this test requires a renderer to run. Optional will enable the renderer where available.
with_audio = false # If this test requires an audio backend to run.
with_video = false # If this test requires a video decoder backend to run.
# Whether or not to compare the image rendered with an expected image
# The comparison part of a test is optional and only runs when `imgtests` feature is enabled
# This requires a render to be setup for this test
[image_comparison]
tolerance = 0 # The tolerance per pixel channel to be considered "the same". Increase as needed with tests that aren't pixel perfect across platforms.
max_outliers = 0 # Maximum number of outliers allowed over the given tolerance levels. Increase as needed with tests that aren't pixel perfect across platforms.
