When using a snapshot object we have access to exactly all
the pixels below it inside the snapshot surface. So, in order
to produce a nice blur, it is necessary to expand this snapshot
and then clip it otherwise the edges will look a bit ugly.
Unfortunately, there are still places where blurs didn't look
so good, as objects below an opaque region would never get
rendered into the snapshot object. So the edges, inside a
snapshot object, around an opaque region would have blur
artifacts.
This fixes that by shrinking the cutout regions by the radius
of the filter. Eg for blur this is the blur radius.
The test case in elm_test can exhibit this fix very clearly:
a red glow would be visible around the opaque rectangle, but with
these changes we instead see the blurry edges of the objects
below the rectangle.
This will be most useful in a special case, where a filter is
used in a window decoration, applied to a snapshot object.
Another optimization that might be wanted is passing a list
of update regions (from the proxy or snapshot).
The filters don't support the obscuring region yet, only some
of the high-level logic is implemented.
If anything in the canvas needs redraw and a snapshot object
happens to intersect with the update region then it was redrawn,
even if all objects below it hadn't changed. This has an insane
performance impact when you apply a blur filter on the snapshot
object. Walking the object list will always be cheaper than
rendering the snapshot!
Note: Added a FIXME comment and forced clean_them to be true
because some odd behaviour happens when breaking with GDB and
the array snapshot_objects keeps growing at each frame (I guess
only if we miss a frame or something like that).
This reuses the existing mask infrastructure, but adds a color
flag to use the whole RGBA range, rather than just the Alpha
channel.
Filters are still very slow (glReadPixels and non-optimized use of
GL buffers...), but this is progress :)
Alright, so this is a massive patch that is the result of
trying to get rid of unused or poorly implemented classes in
ector. Originally ector was meant to support VG but extend to
things like filters as well. At the moment, ector's design
makes it quite hard to plug in the filters.
For now I think it's easier to implement the GL support for
the filters directly in the engine, where I hope to interfere
as little as possible.
This massive patch keeps only the required minimum to support
a versatile gl buffer that can be mapped, drawn or rendered to (FBO).
It's extremely inefficient as it relies on glReadPixels and lots
of texture uploads, as well as conversions between ARGB and Alpha.
Another type of GL buffer is a wrap around an existing GL image,
but that one is read-only (map or draw: no write map, no FBO).
No, all the filters run fine, and the high-level implementation
(evas_filters.c) does not need to know whether the underlying engine
is SW or GL. One problem though appears with the blending or blurring
of some Alpha buffers, the colors are wrong.
This patch removes more lines than it adds so it must be good ;)
This is an attempt at refactoring the filters code so I can
later implement GL support. This patch adds a few extra changes
to remove avoid calling functions of libevas from the software
engine: use the draw functions from static_libs/draw rather
than evas_common APIs.
Summary:
If the last item before ellipsis item has bigger width than its advance,
evas_common_font_query_last_up_to_pos() function can find wrong ellipsis position.
When Evas finds a position for non last item, Evas must care about additionally
available space for glyph's width of the given x position.
ex) the last item's glyph before ellipsis item has a tail to draw above the ellipsis item.

clip_dirty is called A LOT. Unfortunately this patch does not

**********************
Note about this merge:
After this series of patches, the CPU usage for a certain test
case has significantly gone down:
Based on c0e6a8d698c17fc16f9b67fc9 (upstream before git push):
NS since frame 2 = 28910806786 , 2937 frames = 9843652 / frame
After this patch:
NS since frame 2 = 19218592951 , 2928 frames = 6563727 / frame
1.18:
NS since 2 = 13105584220 , 2961 frames = 4426066 / frame
As we can see, 1.18 remains *much* better than 1.19. I'm still
struggling trying to figure out why (clip_recalc is called more,
but the call tree is hard to decypher).
The test case is:
EINA_FREEQ_BYPASS=1 ELM_TEST_AUTOBOUNCE=100 \
elementary_test -to "Scroller 2"
EFL was compiled with GCC 6.3.1 with -O3 -g
@optimization
This function was moved out of inline (see d7c6fca6c0) but
unfortunately the early checks at its beginning are likely
to result in an early return. Inline this part so we get back a
better performance. Inlining the whole function does not improve
the performance, as GCC simply gives up with inlining.
Note: Between 1.18 and master the number of calls to clip_recalc
has simply blown out. It is thus crucial to find out where those
calls come from but also micro-optimize the function itself. This
patch does the latter only.
@optimize
In relative smart move, we only need to check once that the object
is indeed a valid smart object. This drops the call count from ~1.02M
to ~785k.

The previous patch (b184874fa5) was preventing
post-event callbacks from triggering any form of input event,
including side-effects due to mouse,in. In fact by tracking
which exact events we want to post-process we can support
proper recursion. This fixes crashes in Bryce.
I'm not changing the documentation as this is still a dubious
code design.
Fixes T3144
Fixes T5157
See T3144 that I marked as Wontfix.
Bryce in E manually feeds events from a post-event callback
resulting in Evas going insane and leading to frequent crashes.
The ideal solution (for E) would be to ensure that everything works
smoothly, the input event data is valid up until the post-event cb
is called, etc... Unfortunately, with recursive events the exact
order of operations may be messed up: the post-event
I don't want to add yet more complexity to Evas events here (it's
already spaghetti all over the place) so I'm simply blocking any
new event feed when running the post-event callback list.
It's not possible to just freeze the events (I tried, it failed).
**********************
Some more explanation:
post-event callbacks are used to implement reverse-order logic
where the on-hold flag of an input event may be set by an event
listener that does not come first.
Here's a situation to illustrate: scroller A inside scroller B.
As events are propagated from children to parents (assuming the
propagate flag is set), we'd assume the events to go first to A
and then to B, which means a mouse wheel event would make the
inner-most scroller (A) scroll, and the outer-most scroller (B)
wouldn't budge.
But as things are designed, A and B are not simple evas objects,
and the actual event-catching object is a top-most transparent
rectangle (top-most in Z stack order). Since A is inside B, B's
rectangle BR is over A's rectangle AR, thus catches the wheel
event first. But in terms of UX we still want A to scroll, not B.
The solution then is to reverse the event processing order and
post-event callbacks are the way to do that. This comes with the
consequence that the event_info needs to remain valid until the
post-event is called, and stay the same (so that the on-hold flag
set by A can be read by B).
Recursive events (by explicit feed or modifying the canvas so
that mouse,in or mouse,out are triggered) mess with this logic,
and trigger the post-events too early (event is not fully
processed) or too late (event_info is not valid anymore... and
crash!).
Thanks @raster for explaining the goal of post-event callbacks!
After a long search I found that fileselector was not calling
super.group_del on deletion, leading to the use of dangling pointers.
So let's verify that group_del is properly called.
See T4598
A use of the post event callback in Bryce triggered a double free
as an event was being processed but not yet removed from its list,
leading to an invalid state of the Eina_List.
Also remove obj from struct as it is unused.

several calls, specifically evas_object_change_reset,
evas_object_cur_prev, and evas_object_clip_changes_clean that are
called directly or indirectly as part of evas render on at least every
active object if not more, were doing full eo obj lookups when their
calling functions already all had the eo protected data looked up.

of course other things "increase their percentage" as oe overhead now
dropped, and things seem to move around a bit, but it does make sense
to do this with no downsides i can see as we already are accessing the
protected data ptr in the parent func.
This should save a bit of memory for all image & text
objects. This exploits the previous patch for the post-render
job queue added to evas, and simplifies this bit of code.
i found evas_common_draw_context_apply_cutouts() was procsessing 300+
cutouts and as it's O(n^2)/2 to try and merge adjacent rects for
cutouts this really performs like complete junk. we apply cutout rects
a LOT. this is not the best solution, but it's quick and much faster
than doing the clipouts which drop framerate to like 1-2fps or so in the
nasty case i say (tyls -m of photos in a dir with a 2160 high
terminal).
this figures out the target area to limit the count of rects
significantly so O(n^2) is far far better when n is now < 10 most of
the time. and for the few operations where it's a high value this now
uses qsort to speed up merges etc. etc.
@optimize
This fixes evas_object_image_save after changing the orientation
of an image in the GL engine. In SW engine the pixel data is rotated
in memory, so things worked fine from the beginning. In GL we may
have to go through loops and hoops in order to rotate and fetch the
data from the GL texture.
This should fix ce45d44.
This reverts commit 4e110a34bf.
Urgh. I'm stupid. Conceptually I still like the idea of the
region proxy, that only renders part of the source object
in a proxy surface. The problem right now is that the proxy
subrender mechanism renders to a surface that belongs to
the **source** and not the proxy object. As a consequence,
the region would become a property of the source, rather than
the proxy, which is not at all the intention of the original
patch. In other words, everything would fall apart if an object
has more than one proxy, for whatever reason.
I realized that when trying to actually test the region proxy.
It didn't work at all. Revert for now.
Only the size of events_whitelist isn't enough, because in some
cases the user may be disabling the usage of a specific seat.
Considering the following scenario, the issue will easy to understand:
- an application with two entries (one to be used by seat 1 and other
by seat 2)
- the first seat is announced - it is enabled for entry 1 and
disabled for entry 2
- the second seat is announced
Before second seat is announced, the first seat would be able
to input the entry 1, because the events_whitelist of such
object will continue empty.
So a flag will be used to identify an object with active
filter.

Always assume use_mapped_ctx as true, the caller of evas_render_mapped
must ensure that the context is suitable (so either clean or contains
the appropriate clip info).
Also pass do_async to mask_subrender. For now it will always be reset
to false as the SW engine requires sync render to convert from RGBA
to Alpha (not great). The upcoming GL async engine should be able to
render masks asynchronously without any problem.
It was never used, except in dubious situations (most likely a typo).
A clean context is now used in the top-most call to
evas_render_updates_internal_loop.
This will allow partially rendering a proxy in a smaller image,
limited to the specified region. At the moment, this will allow
apps to create proxies of very large objects and let them deal
with the geometry & clipping.
This is not directly solving the issues with adding a filter
to textblock or the infinite page scrollers.
@feature
The hash implementation demonstrated that too much memory was being used
to store the Evas_Object_Pointer_Data. In order to reduce the memory usage
this patches now changes the Evas_Object_Pointer_Data storage to an Eina_Inlist and
now Massif profiles shows that the memory usage was drastically reduced.
With this new API one can block or unblock keyboard, mouse and
focus events that was originated from a seat. This is useful to
create applications that wants to establish some kind of seat segregation.
After @cedric's commit 6427c77707 we end up with E
not working in Xephyr, because evas_common_shutdown() is called
too many times (init_count == -1). So I'm being paranoid and
tracking whether Evas has initialized or not evas_common. That
way we end up with exactly the right number of inits. We even
reach 0 after E shuts down :)
This patch introduces possibility to enable key locks and modifers by seat.
It's very useful when the user has two keyboards attached to different seats.
This patch introduces the possibility to set the pointer mode and
query other properties like current position per pointer device.
The old API will still works, however it will only act on the default seat.
evas_object_clip_recalc is big. it's fat. it shouldnt be inline. so
make it a real function. being inline just hurts performance by making
our code bigger, hurting l1 instruction prefetch and cache
performance. this function isn't small. it's huge and should not be
inline basically because of that reason.
also throw in some likely/unlikely hints etc.

part of rendering is figuring if obj is inside current geometry.
before we had to actuall poke around inside the object. this moves the
geometry into the active object array so the data is fecthed fast and
already there for filtering as this is the most likely thing to filter
out an object.
unfortunately this seems to have some bugsd and i'm baffled why, so
leave it there and ifdefed out for now for suture hunting.
evas render in phase1 in order to generate update rects, active,
render etc. object arrays has to walk every object in our tree. this
is a waste of time if we already have walked objects in a previous
frame if they havent changed, so cache this data in render cache in
smart objects to avoid re-walking and now just dumbly "memcpy" these
cached arrays into the master array. i have seen cpu usage by e drop
like about 15% in the sencarios i'm looking at "enlightenment
compositor with some window updating animation all the time, but most
other stuff being static).
