Ref T4623
v40 bytecode interpreter is official as of freetype 2.7.
The results don't look so good at the moment. The text looks and glyph
positioning seem worse than they were with the previous v35 interpreter.
So, in the meantime we'll keep using v35, just so everything looks
normal again.
Although the v40 is relevant since around 2.6.3, I rather not do any
FREETYPE_MINOR checks in this patch, because distributions might ship
previous versions with the other (v38) interpreter enabled.
We've been pinning the render thread for every EFL process to core 0.
This is a bit silly in the first place, but some big.LITTLE arm systems,
such as exynos 5422, have the LITTLE cores first.
On those systems we put all the render threads on a slow core.
This attempts to fix that by using a random core from the pool of fast
cores.
If we can't determine which cores are fast (ie: we're not on a
linux kernel with cpufreq enabled) then we'll continue doing what we've
always done - pin to core 0.

I got an issue report about map rendering.
After investigated, I found that was introduced by data overflow.
For fast computation, evas map uses integer data type rather than float,
that gives up some range of data size.
So, if vertex range is a little large but still reasonable,
polygon won'be properly displayed due to the integer overflow.
We can fix this by changing FPc data type to 64 bits (ie, long long)
But I didn't do yet though I can simply fix this costlessly.
By the way, my test case map points are below.
0: -1715, -5499
1: -83, -1011
2: 1957, 5721
3: 325, 1233
and gl result is perfect but sw is totally broken.

This brings support for the eo api for external buffers (like
the old data_set / data_get). The new API now works with slices
and planes.
The internal code still relies on the old cs.data array for
YUV color conversion. This makes the code a little bit too
complex to my taste.
Tested with expedite for RGBA and YUV 422 601 planar, both
SW and GL engines (x11).
It's entirely possible that a system doesn't have a cpu 0, so
when we try to pin all our render threads onto processor 0 we
may fail.
This results in some very connfusing build breakage when
edje_cc hangs up because its render thread didn't start.
So, if starting the thread with affinity fails, let's try without
affinity.
(This is trivial to reproduce - just use sysfs to turn off cpu0
after boot.)
@fix
this speeds up downscaling of images by somewhere between 1.8 to 3x
dpeending on case and cpu etc. - this is ONLY for downscaling of an
image buffer betweeb 50% width and/or height up to 100% of width and
height. it's a special case optimization that cuts down the complexity
of the full super sampling filter to just do a bilinear interpolation
which is actually strictly correct for this size range and shouldn't
drop quality. it uses fixed point (16.16) to do the sup pixel sampling.
no mmx/asse or neon, but we could actually easily use it as we do use
mmx/ee and neon in the bilinear upscaler to do interpolation so this
would work here too. it just requires time and effort to make yet 2x
more special cases and use the ASM to do the hard slog here.

This is essentially a cleaner redo of ef817f15f0.
Logic should be exactly the same as there, the different is that this
one shares the code between OT and non OT.
Please refer to that commit for more information.
This was not done correctly. This split the code, which is essentially
the same for both OT and non OT. It's the same logic with some minor
additions for OT, so most of the code should be together.
This reverts commit ef817f15f0.
Fixes T4068.
Simply querying the last glyph to determine the width of the glyph sequence
won't always work, as OT can have negative offsets (adjusts the placement of a
specific glyph better).
The solution is to calculate the "max width" of some sequence that will
guarantee us proper width results. The worst solution would be to iterate on all
the glyphs and sum up the max width. This is a bit impractical. Instead, we will
inspect just the "cluster" of the last glyph, if one exists.
This should have no performance impact on trivial cases, and very little impact
on the others.
@fix
some font glyphs are still allocated after tyhe last gl window is
freed which means we can't make current anymore to free textures after
that. this fixes that by flushing gl texture info from the font cache
when the last gl windows are gone.
@fix
We were copying a user defined string into a fixed size buffer
without doing any boundary checks. This commit fixes that.
Also cleaned up similar code that was using hardcoded numbers.
@fix.
Summary:
evas_common_language_from_locale_* functions kept static pointers
inside of its functions. Once these function was called, it was never reset.
It made big problems for harfbuzz and hyphenation. Also, Elementary
provides elm_language_set() API. Then we need to support it fully.
@fix
Test Plan: Test case for hyphenation is included in Evas test suite.

this works with 7166e6b859 and fixes a
leak added because ... free does not free!
evas_common_draw_context_cutouts_real_free(0 now actually frees the
rects, but evas_common_draw_context_cutouts_free() before did not.
@fix (follow on from 7166e6b859)
this fixes the fix 4d6a8a7fce to be
portable to platfomrs that do not support __thread - seemingly openbsd
does not (argh!) and maybe others. so on these platforms then they
dont get the optimization of keeping a cutout rect pool to avoid
re-allocation.
this also every 4096 draws "resets" the cutout cache so it doesnt
expand and stay expanded forever.
@fix
several draw funcs keep a static Cutout_Rect *rects = NULL; variable
to cache cutout rects to avoid re-allocating them a lot etc. this is
fast and handy but we may use these from multiple threads. thats bad
.... mmmkay. so this fixes it the dirty way - makes them thread local.
:)
this fixes T3348 - the crash mentioned by @zmike
@fix
Width calculations should consider the x_bear. This has been leading to
inconsistent results between wrapping calculation during layout and the
final formatted size.
Also, we should stop our walk only when exceeding 'x', so changed "<="
to "<".

Summary:
Previous implementation loaded data from memory first and then checked the borders.
Here I check the borders first as it is for C implementation.
This prevents read of non-accessible memory.

Those APIs should provide a cleaner interface than the
old data_set/data_get APIs, by making sure the operations are
atomic (ie. no need to call size_set, cspace_set and then data_set).
padding/duplicated borders are not supported.
TODO: Implement legacy API on top of the new API, instead of
this quick patch
Summary:
Evas Text, Textblock, Textgrid keeps own language information.
This language information could be vary from the result of setlocale().
Especially, Evas Textblock supports <lang> tag. The language could be
changed in the middle of text. All of these language has to be used
for harfbuzz shaping.

See T2865.
Since Harfbuzz 1.1.0, terminology displays fonts funnily aligned to
the top. This is apparently because until 1.0.6 the y_offset was
always 0 for all glyphs, but since 1.1.1 the offset is actually
set.
This is a TEMPORARY fix. There might be an underlying issue left
here.
Harfbuzz changed behaviour in this commit:

[ft] Remove font funcs that do nothing
Summary:
It adds evas_object_paragraph_direction_set, get APIs.
The APIs set or get paragraph direction to/from the given object.
It changes BiDi calculations and affect the direction and aligning of text.
It doesn't have any effect to text without Fribidi library.
The default paragraph direction is EVAS_BIDI_DIRECTION_INHERIT.
If dir is EVAS_BIDI_DIRECTION_INHERIT, paragraph direction is changed
according to smart parent object. If there is no smart parent object,
paragraph direction works as EVAS_BIDI_DIRECTION_NEUTRAL.

This function was trying to infer from the LANG env var, though it should
have just queried the locale all along, as the language we want is the
system's text language, and not necessarily the LANG variable's value.

Typos, lack of NULL check, excessive sizeof(type) not matching
the object type, no border set, etc... This all lead to a crash
and then no render (with an error message and then without...).
This also simplifies the implicit loading of ETC1 as ETC2 when
supported by the driver.

Actually copying max is pretty useless and super slow. We usually have something
like 1024 slot in a context, but a very small amount of them are acutally active.
It would be better to actually do some kind of copy on write technique here, but
as Eina_Cow doesn't handle array and we are close to a release, let's be
conservative.
the overhead didnt show up in y tests. do show up with certain
expedite tests. hmmm. last time i messed with region code it was
actually same speed as tiler. bonus was it was fully accurate.
valgrind pointed this one out. we access freed memory when we dup a
context because the context CONTAINS ptrs to things like rects for
cutouts. we didnt dup these. use the proper context dup call (and
properly ref pixman color image too). this was a random bug/crash
waiting to happen and valgrind caught it. suprising it hasnt turned up
before :/
@fix
this optimizes draw ctxt cutouts by skipping small ones and
remembering the last cutout added so it isn't double-added as well as
extending the minimum cutout array to 512 and going up in blocks of
512 instead of 128. also optimize the clipping code a bit more.
