[BUG]: Render disparity between two Animate versions

[ACrazyTown]

Describe the bug
While I was testing around some stuff with FlxAnimate I found out that the same symbol renders differently from two different Animate CC versions.

Explain how to recreate the bug
Might not work with all symbols, but export a texture atlas from Animate 2019 & 2021 and display them using the following code:

var animTest:FlxAnimate = new FlxAnimate(50, 50, "[Path]", {Antialiasing: true});
animTest.anim.addBySymbol("a", "[Symbol Name]", 24, true);
add(animTest);

animTest.anim.play("a");

What should happen?
The symbols should display identically.

Adobe Animate Version
Animate CC 2019 19.2.1 (build 408)
Animate CC 2021 21.0.6 (build 41649)
FlxAnimate version is the one from Haxelib

Additional context
How it displays when exported from Animate 2021:

How it displays when exported from Animate 2019:

I can also provide the fla if it can help out with debugging.

I'm gonna investigate this a bit more, but as of right now I've found out that Animate 2020 displays identically to Animate 2021

[ACrazyTown]

I figured it out!!! sort of.

The eyes didn't display in 2021 because they were a "Drawing object", I'm guessing FlxAnimate can't parse these yet? The anim plays fine, except for the border shape which wobbles around when the character moves.
This doesn't solve all of the issues though as in 2019 the border doesn't even exist and in 2020+ it wobbles like I said earlier.

Looks like my 2019 atlas didn't include the border. Oops. But the wobbling issue still persists.

Would you please provide the fla which contains this animation?
I am sorry for not replying sooner about this matter, but I was already occupied with making the new version of FlxAnimate.

Thanks for your time and sorry for the inconvenience.

I'll send you it on discord, dw its okay

I sent a message regarding this issue already on Discord, but I believe this would be good to send it here too to have a record.

"The eyes don't seem to be rendering correctly because, to put it in a way, the eyes are connected to the legs and arms as a whole sprite
from what I can tell, Drawing Objects are just a fancy way to group drawings but not animations, and so in texture atlas it seems to just overlook that and think it's all a single drawing, and it misleads Adobe Animate
the wobbly border is a render error in the matrix (as weird as it can sound) it's basically a render error which basically, the texture atlas is rounding the matrix values."

Again, I am sorry for not being able to help, but this seems that Adobe Animate isn't rendering the texture atlases properly.

Closing because this is more of an Animate issue rather than a FlxAnimate issue
