[4.11.3] Different behaviour for action 21 between zdoom and dsda

[SuaveSteve]

Hello!

It looks like Zdoom interprets special 21 (Floor_LowerToLowest) as a platform or lift when the UDMF namespace is dsda.

Consider the two attached wads. Each is the same except for the namespace being different in the TEXTMAP.

There's a pillar with the line action 21 with use activation. On activation, DSDA will lower the floor correctly for both wads. Zdoom only does it for the one with the zdoom namespace.

The "dsda" namespace is as yet unsupported.

This is a future project that will need to be addressed, but for now, I'm moving this to features.

[Graf Zahl]

dsda is just a subset of zdoom. Unless we need a feature filter it should just be allowed to pass through as-is.

[Rachael]

Alright I will redirect it then.
