NEWCOMBOSDM quest rule

[ZoriaRPG]

I'm afraid I'm confused about what the problem is then... @ZoriaRPG can you elaborate?

In any case, Zoria, the TL;DR of this thread is that any change must

1. preserve backward-compatibility of 2.50.x with respect to quests saved in old versions of ZQ;
2. preserve backward-compatibility of master with respect to 2.50.x (from the perspective of master, 2.50.x *is* an "old version" even though it's not released yet!)

These are "iron laws" in the sense that a change that breaks one is almost always a bad change, regardless of its other merits. I rolled back the NEWCOMBOSDM rule because it ran afoul of (2).

Is it safe to edit zdefs.h, ffscript.cpp, and the jwin panes to add this rule to master? If not, then this is just delaying 2.53 indefinitely, until it is safe to edit those files.

If so, I want to get the bitmap offset fix rule in at the same time, as that also needs to go into 2.53.

It would have been nice to alert me of this issue before adding a reversion push. I will need to re-do the same work, again, to reverse it, although given that I need to add in a rule for bitmaps, that is less of an added workload. Still, if it was safe to edit master, then you could have asked me to fix it there, instead. It is a very simple fix, and migration later is not applicable here, as this is a compatibility rule for the engine, that need be read-only in future builds. ( Setting it for 2.60 makes no sense.)

I will probably invert it though.
