565. what it does is it's a half-way house between no dither and "small
dither mask". what is does is change the "rounding" between odd and even
lines. the resolt is not as nice as small (or large) dither mask - but its
almost "good". it gives a horizontal-blinds like look to dithering. it's
almost as fast as no-dither in my tests on a core2 (of course making lots of
use of branch prediction or conditional instructins - whihc arm nd x86 have).

ProFUSION funded the rework of DirectFB engine, it works quite well,
please report problems with it and be sure to try to uncomment the
following lines to see if it helps:
evas_engine.c: (uncomment if you notice problems)
//#define DFB_USE_EVAS_IMAGE_DRAW 1
//#define DFB_USE_EVAS_RECT_DRAW 1
//#define DFB_USE_EVAS_POLYGON_DRAW 1
//#define DFB_UPDATE_INDIVIDUAL_RECTS 1
polygon.c: (comment if you notice slowdowns, but may lead to visual problems)
#define USE_SPAN_RECTS 1
You can also turn on debug by uncommenting in evas_engine.c:
//#define DFB_DEBUG_IMAGE 1

that's about it. a bit hacky - but works and frankly.. the idea is that u'd
set a scale factor once really and not change it per obj... most likely.

This class covers the most common cases, usually its sub-classes will
have to implement resize and override one or two methods at most,
making the smart object usage less error prone and easier.
Default behavior is:
- add: creates a hidden clipper with "infinite" size;
- del: delete all children objects;
- move: move all objects relative relatively;
- resize: not defined;
- show: if there are children objects, show clipper;
- hide: hides clipper;
- color_set: set the color of clipper;
- clip_set: set clipper of clipper;
- clip_unset: unset the clipper of clipper;
Documentation explains an easy way to inherit from this class and
still be able to use overridden methods.

Some people is using it for some time now without problems, so I'm
adding it to SVN to get some broader use. Remember to recompile ALL
libraries that depend on Evas as it will change the
EVAS_SMART_CLASS_VERSION and old classes will fail to load.
This will also change Edje so it will postpone _edje_recalc() to
render time, calculate() callback, however some methods will force
early recalculation.

xrender/gl engines dont even implement the drawing and need to (but are
stubbed out).

* add a ressource file that set the video management
as non legacy. It forces device that are in vga to
run in vga and not in qvga with gapi
* use c++ calls to display error messages in evas_wince_ddraw.cpp.
It removes a problem during linking with some versions of cegcc
* minor fixing / formatting

This will check both function and data before removing the callback,
this is useful when you have lots of children monitoring parent, when
one child want to remove its monitoring function, others will remain.
Name is quite difficult to choose, I opted for "_full", but could be
"_with_data" or similar.

Image_Entry flag structure. This fix a bug with 16 bpp software engine.
* Change image loader module API to take any Image_Entry. Same goes
for evas_common_image_premul and evas_common_image_set_alpha_sparse.
* Use new eet API: eet_data_image_read_to_surface.

This patch fixes the problem with bitfield of signed types (ie: char),
where the bit would be used for the signal, so 1 is considered -0 and
thus 0.
Move all the single bit fields to Evas_Bool, making it clear and also
avoiding these problems since Evas_Bool is unsigned char.
SVN revision: 34631
2. free then malloc otherwise realloc might ALSO have to memcpy if it cant
resize the segment whihc means overhead we dont need/want.
SVN revision: 34441
By having a layer as a short (16 bits) we can pack it together with
the bitfields, saving 4 bytes per sub-struct, 8 bytes in total, also
bringing the struct down from 4 to 3 cachelines on my laptop.
Rationale: layers are mostly used to differentiate groups of objects
and they stacking, usually we have few layers and we use very large or
very small numbers to make a layer be at the top or at the bottom, but
usually we don't need so many layers.
Caution: code that use values like 999999 will break, so fix your
code! I'll provide another patch to fix all the CVS using these large
values.
SVN revision: 34420
This saves 20 bytes, bringing Evas_Object to 200 bytes, by moving data
specific to smart objects to their own struct (Evas_Object_Smart).
There is still one remaining member that could be removed:
smart.smart, this is used mainly to identify if one object is a smart
object or not. One possibility would be to add a bitfield to state
that, but another possibility is to check Evas_Object::object_data
and see if it's a smart or not.
SVN revision: 34419
Interpolation color_space (now ASHV or ARGB) was being used inside a
struct with 4 byte alignment. Remove it from the struct and make it a
bitfield so can be packed with the other fields. This saves 2
integers, so 8 bytes.
SVN revision: 34418
This is a repack of bitfield members, was tested on GNU/Linux + GCC 4.1.2
and works fine. Needs further testing on other compilers.
SVN revision: 34417
Size hints are useful, but wasting 36 bytes for it on every object is a bit
too much: clippers and lots of other objects will have no need for it.
Now it's a pointer to a struct that will be allocated just when some value
is set, wasting 4/8 bytes more for the pointer when it is used, but saving
32/28 bytes when it is not.
This will also help to have alignment properties in future, that can come
as hints, without too much impact on memory consumption.
SVN revision: 34412
This will help the use of Evas_Bool to define bitfield structs like in:
struct s {
Evas_Bool a:1;
Evas_Bool b:1;
Evas_Bool c:1;
Evas_Bool d:1;
Evas_Bool e:1;
Evas_Bool f:1;
Evas_Bool g:1;
Evas_Bool h:1;
Evas_Bool i:1;
};
It must be unsigned or it would use the signal bit, having "a == 0" to
be true anyway, as it would be just +0 and -0.
SVN revision: 34362
The engine is not entirely working right now. Recent devices which
supports the raw frame buffer should work though. But having it in
cvs will help me as I'm coding it most of the time "blindly" (no
device to test it)
* minor formatting in the top evel Makefile.am too
SVN revision: 34354
* formatting
* put WIN32_CFLAGS in AM_CFLAGS and not AM_CPPFLAGS, as it is where it belongs
* rename create_shared_lib to lt_no_undefined
* pass -Wl,--enable-auto-import to libtool when compiling with cegcc
* add files to EXTRA_DIST only when they are not in _SOURCES or _include_HEADERS (they
are added anyway)
SVN revision: 34353
Move pointer_mode (size 4) before bitfields, leave 'delete_me' as it's
a byte, this still have 2 bits left from unsigned short and another
byte around delete_me to make it grom from 244 bytes.

* use the pixman library for the region code (it is required, now). That
libray can be found in the cairo ftp.
* use the new xcb_image api that is in git repository. There is still a
seg fault occuring because of xcb_image. I'll commit the fix in git
next week.
The performance are not good at all. With expedite, 360 fps compared to
the 470 fps with xlib. I don't know why yet.

Although I used 3 lines comments to state it was not required, it is
required because none of the values accounted includes the '\0'.
SVN revision: 33940
This should provide correct code in a simpler way by sharing some of
the common code among functions.
Tested with E17 basics, require some applications with extensive usage
of textblock manipulation to do validate results.
SVN revision: 33939
Code was not tracking the real size of the allocated memory and was
increasing the string size by one, so the '\0' was being accounted and
the string was being truncated visually.
Patch will remember the exact allocated size and just increment the
string size by the added string, not including it's null-byte
terminator.
This is based on Cedric's BAIL patch set 'evas_object_textblock more
character fix', but doing the minimum to fix the problem.
PS: this code will be rewritten to share some implementation in next commit.
SVN revision: 33937
This is an initial cleanup, basically I removed all the DirectFB
accelerated calls and moved it to software common. I do plan to
gradually bring these back later, probably blit, rectangle and line

As aclocal may be called via autogen.sh during the Debian build process
add an explicit build dependancy on pkg-config which includes
/usr/share/aclocal/pkg.m4 which provides the PKG_CHECK_MODULES macro.
SVN revision: 33781
libgl-dev is now a virtual package provided by libgl1-mesa-swx11-dev and
libgl1-mesa-dev, so one of these packages needs to be the build dependancy
instead of libgl-dev.
libgl1-mesa-dev seems to be the most logical choice as it can
be installed with minimal disruption on a vanilla install.

This fixes the prototype, however it still issues a warning about a
real bug: calling evas_hash_modify() during evas_hash_foreach()
SVN revision: 33710
The previous commit just removed the warning, but it was not the ideal
solution. The class is really a constant, nobody should change it
after it's assigned.
SVN revision: 33709
As agreed on IRC, evas_hash_foreach() now takes const, to make clear
that hash shouldn't be changed. If one wants to change he must do a
cast and return 0. However this will require users to be updated in
applications.

1. configure/build changes to allow cross-compiling painlessly
2. pager module namespace changes - this was still dirty afdter the namespace
cleanup, so clean it up
3. add a powersave subsystem - doesnt have an "automatic" way to turn on and
off right now, this i think is best provided by modules (that do things like
monitor acpi status's (eg close lid of laptop), AC power status etc. etc.
this allows e to nicely defer "power" expensive actions to avoid disk
spinups etc.
4. move to use the new ecore poller system - discussed long ago as part of
power management/saving issues. now it exists
5. add a canvas idle flush call that helsp cope with the new shm greedy
software x11 engine stuff
6. use the new powersave subsystem where appropriate
7. fix non-zeroed/initted memory access in e_fm_main
8. fix mem leak for e menus
9. remove ipc handlers for changed/removed config values
10. use animaotr not timer for menu scrolls - then menu scrolls obey the fps
config
11. fix up timer/poll happienss of cursor idle stuff
12. remove avoid damage from popups for now - causing problems
13. change battery and temp readouts to b e shorter so they fit
14. pager can emit signals on focus change for mini-windows now
15. temperature module now uses a slave process and uses stdin/out to talk to
it and get output - this makes e smoother as in my expereicne i found getting
the temp on my laptop actually took like 200ms so e "hang" for 200ms while
reading the acpi files - so now the subprocess does it and just writesa back
to e when it gets it.
ecore:
1. add ecore_pollers. see the documentation on them in doxygen comments :)
2. fix timers to only go off when they have to - bug there that made e's
select time out a LOT more than it needed to. defensive coding hid the
problem. now fixed. e should be much more power friendly now.
3. formatting/niceness in ecore_exe stuff
4. some comments on comments with SIGIO ideas vs. select
5. add call to be able to add an idle enterer at the start of the list of
them, not just the end (as has been the default)
6. fix ecore_evas to support auto evas idler calls after 0.5 secs of idle in
all canvases - and to do it right
7. if argb destination - set the shape EVENT shape (to mask out events in
transparent regions much like shape does withotu translucency)
8. in ecore_x add support for the event shape
evas:
1. fix cache to work properly and not just always fill up (as it seemed to
like to think cahce useage dropped below 0 when it didnt and thus just
over-fill)
2. software x11 engine now ONLY uses shm segments - no ximages over the
socket. this ximage hack was there to avoid the 2 round trips involved in
setting up an shm image - now i mitigated that wih an shm image cache pool.
it keeps shm images around and repurposes them for new update regions if
appropriate. this means many fewer shm creates (about 1/100th the number) and
since we recycle the memory less 0 memory page filling by the kernel - in the
end, i recorded about a 10-20% speedup over the old software x11 engine.
simple tests i have seen up to 120% speedups. idle flush now does something -
it frees all the cached shm segments. it has a hard-coded limit of 4mb worth
of shm segments (or 32 segments - whichever comes first) to keep around. once
can never complain much about speedups methinks :). also evas will defer sync
until the NEXT frame is written - this means evas can calculate the next
frame of data while x dma's/copies the images to the screen at the same time
(if you hve a dual core or multi-cpu machnike or your xserver is able to use
DMA to copy image data to the screen/video ram then this should see a decent
speedup).
SVN revision: 33448
can't test it on a GLSL card, so I hope it didn't break anything. If
something is broken, feel free to revert! (but it would probably just be
related to the way it detects GLSL support at l.78 of evas_gl_context.c)

* when it is used and when another --enable-foo is passed, if foo is
not found, configure fails and displays an error message.
* when it is not used, the old behavior (auto-detect) is not changed: if
--enable-foo is passed and foo is not found, configure does not fail.
