Note:

AntiAlias tool will soon be deprecated (obsolete).

It will be changed to use a GDI+ canvas internally, as GDI+ canvas does anti-aliasing of diagonals and curves in a much better (and faster) way.

For FireMonkey this tool was already not available so its not a problem.
Regarding FireMonkey, anti-aliasing is a global setting at TForm level, not at control or canvas level.   (The Form1.Quality property).

btw: 
Currently FireMonkey antialias is disabled by default in iOS platform.


The TAntiAlias tool will still be available and compatible. 
Setting AntiAlias to Yes/No will simply set the GDI+ canvas AntiAlias property True/False.


About the bug, I'll make sure it works fine with the new changes.

Fixed. 

AntiAlias property now correctly used when loading a *.tee Chart file or at design-time.

When a TAntiAliasCanvas is used, it shows at Chart editor dialog -> 3D -> Render tab.

When its not used, as it is now deprecated (obsolete), it does not appear as an option at "Render" tab.  

(Choose GDI+, as its exactly the same now as TAntiAliasCanvas)
