It's just a prim, ie a function somewhere.
I'm proposing that we name all those prims that are currently numbered
- primitive 1 would become "primitiveAdd" in a similar manner to say
"primitiveDisablePowerManager". This would allow all prims to be
built as plugin components, thereby allowing on the fly replacement of
those plugins (making due allowance for handling retained state etc,
of course). (It's sometihng I've been wanting to see done since 1988;
I had discussions with Alan Schiffman & Peter Deutsch about it way
before I even move to ParcPlace). We would lose the primitive table,
saving a 8 kb or so. Oh and the *really* obsoleteIndexPrimitiveTable,
saving another 8Kb or so.
Some code gets simplified, some space is saved, some flexibility is
added, some bits are freed up in the CM header. THe downside is
someone has to do some work.
