cached item contents should already be hidden by the edje clipper, so this simply
changes their visible state to break them out of the focus calcs
contents must also be explicitly marked as unfocusable during calc-only realize
operations in order to avoid triggering a full focus recalc which will error due
to missing focus adapter in the item block

now that we have a sane and consistent sizing calc mechanism, we no longer
need to be randomly creating jobs to do additional side calcs in addition
to our other multiple bespoke calculation methods
instead, we can now call the calc function directly during the group calc
to perform all the calcs at once and avoid the overhead of constantly triggering
calc jobs
a possible future improvement here could be to remove the _calc_job() call in
the internal pan object's group_calculate, as this is likely a duplicated op
but it will require additional testing to verify
unit test performance (e.g., tree) increases roughly 50-80% after this patch

Summary:
the focus model before was more meant for simplicity and not for
performance, this now is more made for performance.
The performance boost is achived by not using composition anymore,
but rather register realized items by hand. This keeps the amount
of items bound to the size of the viewport.
Additionally item realization that is followed by unrealization
immediately is not resulting in focus calls.
This solves the performance issue from T6580 in regards of focus.
perf results after this:

This patch implements bug compatibility.
genlist internally uses both a tree structure with Eina_List and a flat
Eina_Inlist to track its items. ALL of the items are in the inlist while
subitems appear in their parent's list. As a consequence both lists must
be kept in sync pretty tightly. Obviously this is not done at all and
has led to countless bugs, as soon as tree or groups are used:
- Invalid order of items (visually)
- Invalid order of items with sorted_insert
- Glitches in the matrix
- Crashes with sorted_insert
- Odd/even styles not properly set
- Promote/demote functions broken by design
- Developers send to psychiatric hospitals
- Etc...
Legacy genlist (1.19 and before) used an inlist order that basically
didn't make sense, as it didn't follow the logical order of elements (as
they appear visually). Unfortunately this has "worked" (really, that's a
huge stretch to use this word here) for a long time this way. As a
consequence, some applications (*cough* empc *cough*) have relied on
this order to implement "next album" or "previous album" where the
album title is a group node.
By changing the order of items in the inlist, this has broken the
assumptions made above, and ends up in cases that return NULL, leading
to SEGV. Sure, the app should have checked NULL, but that's not really
the point here. The behavior has been changed.
This patch implements "fixes" for the following functions:
- elm_genlist_first_item_get(): Don't return a parent
- elm_genlist_last_item_get(): Return a parent
- elm_genlist_item_next_get(): return a parent upon reaching the last child
- elm_genlist_item_prev_get(): return a child when a parent is passed
Important notes:
- This does not cover 100% behavior compatibility here. The only way to
have it would be to simply revert the entire genlist code to its
original version and never touch it again, ever.
- An explicit API is required for an application to specify which API
level it targets, so that we can cherry-pick which bug compatibility
features we want to enable. We are already doing this for EDC,
unfortunately.

Summary:
**@feature** T6241
This feature enables genlist to pin an item to viewport which will
be available always for user to view/select.
**Use Case**:
In a big list of music, most times when user finds a song which they
like, before playing that they may want to go through the entire list
to check whether there is some other good songs, but
after seeing the entire list user have to again scroll back to the
position of item which they liked to play it then.
In this case item pinning can be used, so that the item
which they want to keep for future selection can be pinned
and then it will remain in viewport, finally when user want to do
operation on item, it will be readily available in viewport.

This fixes the internal item order index.
Note that groups don't reset the odd/even styles. The
original code wasn't very clear on the intent (setting
to 0 in one case, not increasing the counter in another,
but that was not consistent all over the place). I believe
resetting the odd/even styles at a group boundary would
look great, but this might be for another patch :)
This amends part of another commit, but keeps its feature:
b40a6eb85bf44a genlist: implement list position signals.
See T3086
PS: I've discovered more odd/even issues with the
fileselector in particular. Still working on it...
@fix
It was used to hide "it->item"... but was used less than it->item
itself. Explicit code here is not longer, and just as readable.
This macro I think was harmful to readability.
Simple sed, no real change at all.
This fixes a lot of cases where a genlist node (of any type)
with children may have appeared in the invalid expanded or
contracted state.
Before this patch, the test case "Genlist tree, Relative insert"
looked like below (all items are programmatically added):
> A
> 1
> 2
> B
> 3
> 4
The problem above is that A and B have visible children but
still believe they are in contracted state. This patch ensures
that A and B will be marked as expanded, but will do so without
firing an "expanded" signal and definitely without the
"expand,request" signal.
After this patch, the test case will look like this:
v A
> 1
> 2
v B
> 3
> 4
Which is more correct. Note that this test case does not handle
any expand/contract signal.
NOTE: This is a behaviour break!
This fixes the test case "Genlist Tree, Insert Sorted".
This is a pretty ugly patch... but the genlist code is already
pretty ugly, as it keeps a flat inlist of items (sd->items)
as well as a tree structure in parallel.
Before this patch, the following configuration led to issues:
1
3
- A
- B
Adding item "2" led to a crash. Adding item 4 led to this:
1
3
4
- A
- B
Items A and B lost their parent "3". Subsequent sorted inserts
would lead to insane bahaviour, where for instance "8" would
appear before "3".
This patch fixes all sorted inserts, at the cost of performance
(an optimized code path is avoided). Subsequent patches will
increase the robustness of the tree structure.
NOTE: This is a behaviour break!
Fixes T4850
Summary:
genlist content_get sometimes work weird after reusable_content_get pushed.
cached content is shown even content_get function is not exist or
return NULL.
now cache check item_class instead of item style string.
