Sorry, but full documented code will be committed tomorrow, this commit is needed for the API stabilization.
Major changes in this commit:
1. Changed the textblock node system there is now a linked list for the format nodes and a linked list for the text nodes. Format and text nodes point to one anoter in a matter that will be explained in the source file (will be committed tomorrow). Each text node now represents a paragraph and each format node points to a specific location in a text node.
2. Text/Format nodes are now two distinct data types.
3. The concept of nodes is no longer exposed in the API except for the format nodes which are only slightly exposed just to enable users of the API to cycle all the formats in order to find stuff like anchors.
4. Every node has a PS (paragraph separator) format node pointing to it's end, except for the last one which has nothing. Nodes are only broken by PS's.
5. Changed the BiDi functions to work nicely with offsets in big chunks of text.
More is explained in the email with the subject 'Evas Textblock redesign + edje_entry adjustments' that will be sent tomorrow because of technical issues.
For full documentation about this object wait for the next commit.

* Remove vim modelines:
find . -name '*.[chx]' -exec sed -i '/\/\*$/ {N;N;/ \* vim:ts/d}' \{\} \;
find . -name '*.[chx]' -exec sed -i '/\/[\*\/] *vim:/d' \{\} \;
* Remove leading blank lines:
find . -name '*.[cxh]' -exec sed -i '/./,$!d'
If you use vim, use this in your .vimrc:

Added missing unicode & bidi opts to necessary places.
Fixes lots of compiler warnings.
NB - Not all engines tested. If you spot a problem wrt any specific
engine, please report it.
SVN revision: 50601
Changing textblock and text objects to work with Eina_Unicode instead of utf8 (internally, API remains intact).
Started relying on new fribidi 0.19.2 instead of the old fribidi.
A lot of fixes to the font engine.
Renaming of evas_common_font_utf8_* to evas_common_encoding_utf8_*
This relies on new Eina changes and types: Eina_Unicode, Eina_UStrbuf and Eina_UStringshare.

Subject: [E-devel] 8bpp xcb evas engine
Hi all,
I've implemented the 8bpp grayscale evas engine. It is based on the 16bpp
engine. It would be nice if someone could review the code and maybe commit
into svn. The patches against evas and ecore are attached.

Ouch, that was nasty! src/lib/cache/evas_cache_image.c was assuming
all Image_Entry were RGBA_Image (why?!?!?), thus doing the cast and
having mutexes and other to operate on garbage (possibly crashing due
segv). This happened to be the case with Soft16_Image used by
software_16 engines.
I'm not sure, but this may fix problems that people noticed with
async-render hanging their systems even if not explicitly enabled
during runtime.
I also found it quite strange the number of locks required by this
code! Clearly we could use macros to simplify and avoid bugs, but
maybe some atomic_inc/dec code should be used to remove half of the
mutexes in that code?
/me wonders what kinds of bug more we can expect from this code :-/
SVN revision: 50300
Software 16bpp variants were crashing if using preload as the
Image_Entry that was used by preload did not keep the loader and
module information, since these were only set in the
Soft16_Image::source. Now we copy these members while the source is
live.

Just set the EVAS_CPU_NO_NEON environment var if you want to disable Neon.
The same is done for other specific CPU codes, such as MMX, MMX2, SSE, etc.

The notnull.cocci script from Coccinelle finds places where you check if a
variable is NULL, but it's known not to be NULL. The check can be safely
removed. For example, this code would be caught by notnull:
if (!var) return;
if (var && var->fld) { ... }
It's needless to check again if var is not NULL because if it's in fact NULL,
it would have returned on the previous "if". This commit removes all the
trivial places where this pattern happens. Another patch will be generated for
the more complex cases.

The new wordcache option is an environment variable called:
EVAS_WORD_CACHE_MAX_WORDS
set this to a number between 1-500 to change the cache size.
Larger values (40+) fix regressions in a few of the expedite tests.

Code with side effects is NOT pure. Cdoe where you can ignore the return
value because you care about the side effects should not have WARN_UNUSED...
Please only add such things when you've checked

If you are having any problems with Arabic shaping please make sure you have FriBiDi version 0.19.2 installed at the time of compilation. If your distro doesn't have that version yet, make them upgrade, it's an year and a half old.

The evas_debug functions are just called from MAGIC_DEBUG errors, that
are quite critical, so messages should come out by default, and do
that loud with a CRITICAL warning.
Raster, cedric and others: now that we have Eina as a common
dependency between Evas and Ecore, maybe it is worth to unify the
debug system on top of Eina logging? It already provides "abort on
critical", runtime configurable log levels. I'd say the same about the
magic and safety checks themselves (eina_magic and eina_safety).

Some systems, like the Gentoo, copy the svn contents somewhere before
doing the autoconf, this may result in lack of .svn and thus minor
version "0".
This patch introduces the $SVN_REPO_PATH to say where the svn checkout
containing the ".svn" directory is.

imlib2 bmp loader, but it was imcomplete compared to the bmp
standards, so i actually ended up reading the file format definitions
on line i could find and using lots of test images... wrote a new one.
you can at least view bmp files now. note - i found 1 bmp file that
claims to have an alpha channel (amask is non-empty) and then proceeds
to provide an image with pixels - all alpha 0. so its transparent when
it shouldnt be. beats me but looks like a broken bmp file to me when
it compes to specs.

rendering. to turn on:
1.
configure with --enable-async-render
2.
export EVAS_RENDER_MODE=non-blocking
presto. necessitates some api swizzling (thus the expedite. ecore etc. changes)
the kind of results you get on a desktop:

Samsung Electronics just allowed me to release the first set of ARM neon
patches under the Evas licence. They are silently helping improve EFL and
this another product of their help.
These patches have been tested on a Cortex A8 and show consistent improvement
across the board. For expedite some tests up to 100% improvements, and
practical real world examples show that rendering limited applications show
similar improvements. For instance in one application from 17fps->30fps or
for another 40->63fps.
The patches are pure neon code (intrinsics tend to generate worse code). To
build under GCC you will need a recent GCC and the following C flags:
-mfloat-abi=softfp -mfpu=neon
I also recommend -O2 and -ffast-math.
If you have any problems please let me know.
