While "set" is a tad strong (there's just the one component for now), I
had missed the changes when adding ECS systems. Fixes the segfault at
the end of demo1 (ie, when any center text is printed).
Instead of creating new entities for the text views. This approximately
halves the number of entities required to display flowed text, but also
tests the ability to have an entity in multiple hierarchies (the goal of
the ECS component and system changes).
This means that the component id used for hierarchy references must be
passed to Hierarchy_New and Hierarchy_Copy, but does all an entity to
have more than one hierarchy, which is useful for canvases (hierarchies
of views) in the 3d world (the canvas root would have a 3d hierarchy
reference and a 2d (view) hierarchy reference).
This involved disabling sigils for hipnotic and rogue (not used),
adjusting the number of items views, and moving the two keys views for
hipnotic. Rogue is not yet using the correct status bar pics.
The functionality of the hipnotic and rogue weapon power-ups is now done
by a various mappings instead of separate functions. In theory, this
should make things more flexible, but most importantly, there's a lot
less code duplication.
Sigils can't be flashed as they don't have any animations provided, and
they're not normally as critical. I don't know why items weren't
flashed, but since the pics are there, might as well use them (and the
flashing keys do look pretty good).
I think this makes the purpose of the functions more clear and makes the
protocol logic less dependent on the meaning of some of the updates.
Most of the update functions are not fully implemented yet.
I had forgotten that the cl structs in nq and qw were different layouts,
which resulted in qw's sbar/hud being quite broken. Rather than messing
with the structs, I decided it would be far better in the long run to
clean up sbar's access to the cl struct and the few other nq/qw specific
globals it used. There are still plenty of bugs to fix, but now almost
everything is in the one place.
