Should fix AO not turning on without opening floater first
Cleans up code
Reduces memory footprint, especially when not in use
Removes unused functions and parameters
Decouples AO from Floater class (AOSystem)
Removes duplicate Idle state
Formalizes singleton patterns of globals
Centralizes override handling into override structs
Fall back on simple english notecard explanation when missing config ini
Fixes sitting override playing when sitting is disabled (and acting weird)
Moves the bulk of override handling into override structs
No longer state-based, now tracks using per-struct playing field
(ref viewer-release "MAINT-2564 FIXED Alpha mask does not hide hair in the Outfit Editor" and "MAINT-3399 Hairbase renders incorrectly in edit appearance mode")
Links for teleport offers, show autoresponded with item to muted in local,
autounmute notification (so you can remute easily :P).
Cleanup redundant strings
Also let's now select the proper tab when we input an ID or select a face
with an asset ID that we can find in a tab, but that never works for BOM
when applied.
Not bothering with export at the moment
AIXML"Stream" wasn't even using its stream in its constructor...
Someone clearly hadn't been using ACTUAL C++ for longer than C++'s existence like was claimed
...but then, that's literally impossible, so what could we expect...
And dear lord please stop throwing in constructors...
There are so many better ways to do this...
This use of throwing is why people dislike goto
It's hard to follow flow control that would be better done another way...
One day I'll fix it so it is, until then meh.
Rips out AIFile, since nothing is actually using it anymore and GPL code needs purged.
Added the feature of selecting an animation from combo boxes and it playing automatically if it should be at this moment.
Now for the stuff only developers will understand:
FloaterAO is now a FloaterSingleton, because it should've been behaving that way all along.
Refactors a lot, simplifies a lot, best view without space changes.
Reduces a lot of redundant blocks.
Creates some functions to make things like AOStates easier to get
AOStates are now an enum instead of a bunch of const ints.
Cleaned up includes.
NULL -> nullptr, virtual->override, BOOL->bool, for->foreach
Removed struct_tokens, it was redundant and actually just took up space.
No longer set all the children invisible, their parent does a good job of that.
Relate ComboBoxes to their states, so that we can easily get a setting and do a whole bunch of things with a lot less code.
Remove unused parameters and functions and variables
Remove unused boolean returns from functions.
Don't clear combo boxes just because one id is null.
Sync light state, bound shader, and various gl context states similarly to render matrices.
Texture handles now refcounted, as multiple viewer textures could ref the same handle (cubemaps do this)
Clean up gl extension loading a bit. Not necessary, but only look for ARB variants if not included in current core version. Removed unused extensions.
Use core shader api if supported, else use ARB. (FN signatures are identical. Just doing some pointer substitution to ARB if not core.)
Attempt at improving VBO update batching. Subdata updates better batched to gether per-frame.
There's probably other stuff I forgot that is in this changeset, too.
Todo: Fix lightstate assertion when toggling fullscreen with shaders off.
