This optimizes the GL blur algorithm by reducing the number of
texel fetches (roughly half the number of before this patch). This
works by exploiting GL's interpolation capabilities.
This skips extra tests with image objects that have the
is_opaque() function. That way, if an object is marked as COPY,
rendering of all objects below it will be skipped.
This can dramatically help with performance when flagging a
snapshot object as COPY. This should not be done if a filter is
applied and is meant to blend with the underlying UI.
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).
By simply splitting X and Y blurs in two passes we can improve
the performance of the blur filter a lot.
There is still much to be done to make it really fast and nice
looking:
- implement true gaussian blur (not sine-based approximation,
right now the actual blurs look different in SW and GL)
- exploit linear interpolation for R tap instead of R*2+1 taps
(a tap being a texel fetch)
- downscale & upscale large images with large blur radii
Wait a second though, this implementation is not only incomplete
(no support for box vs. gaussian blur), it's also insanely bad in
terms of performance. Small radii may work fine, but at least blurs
render properly in GL with this patch (no more glReadPixels!).
The shader needs a lot of love, including in particular:
- support for 1D box blur single pass
- support for 1D gaussian (or sine) blur
- use linear interpolation and N-tap filters
- separation of 2D blur in two passes (high-level logic)
- potentially separation of large 1D blurs in 2 or more passes
knowing that 2sigma == sigma + sigma when it comes to the gaussian
bell curve.
This one was a bit more... "fun". I had to add a new vertex
attribute and obviously using a VertexAttribPointer led to
incomprehensible crashes. But a simple glVertexAttrib2fv makes
it work like a charm!
A rare option is not handled yet.
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 :)
This corrects two things:
- the blur filter high-level logic, that lead to reusing some
temporary buffers which contained garbage;
- the versatile gl buffer implementation so that it now properly
switches between the RGBA_Image and the FBO content (yes, this
is insanely slow and inefficient... but it works and that was
the only point).
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:
In previous patch, !w should be replaced with EINA_FLT_EQ(w, 0.0), but it was
replaced with !EINA_FLT_EQ(w, 0.0). This breaks rounded rectangle.

If you define either the macro MY_CLASS_EXTRA_OPS for normal
methods/properties or MY_CLASS_EXTRA_CLASS_OPS for class methods
or properties, which contains a comma-delimited list of ops defs
(i.e. EFL_OBJECT_OP_FUNC(...), ...) right before including the
generated my_class.eo.c file, the definitions from these will
be included in the actual class. This can be used to override
certain things in a class internally without exposing it to
Eolian, or for testing/debugging.

When popup is timeout, notify call hide func, and send time out event to popup.
After popup receiving time out event, popup hide object again,
so hide animation doesn't show.
And notify hide function doesn't send hide signal to block events part,
(but dismiss function send it)
So add that signal.

See the previous commit. efl_provider_find() could not
find a canvas because the event object had no parent.
This restores the slider in E's sound mixer.
Note: Input events may expose the evas canvas object
because of parenting. This will eventually need fixing,
as only efl.ui.win should be exposed.
If 8ff2dffe7c7a21278dis backported to 1.19 then this patch
also needs to be merged as well.
Test scenario:
elementary_test -to "ExtScroller"
Try and modify a slider's value with the mouse wheel. Bad things
were happenning, as the flag ON_HOLD was not properly propagated
from the slider to the scroller. This is because the legacy
event_info structure inside the eo event info was not updated
with the new flag value.
By introducing a new EO only API, which is meant to remain
internal, we can use a single legacy info structure, fixing
this issue.
Note: In the future this API needs to be internal, not protected.
