renpy.display.anim not documented

[trajano]

I noticed that the renpy.display.anim module is not documented in https://www.renpy.org/doc/html/py-function-class-index.html is it going to be deprecated and removed in future releases?

Just asking because I implemented https://lemmasoft.renai.us/forums/viewtopic.php?p=514125#p514125 which uses the APIs in that module.

It's retained for compatibility with older programs, but I'd recommend not using it in newer designs. Should we have a major compatibility break - like moving to a Python 3 Ren'Py - I may consider removing it.
