2. free then malloc otherwise realloc might ALSO have to memcpy if it cant
resize the segment whihc means overhead we dont need/want.

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.

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.

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.

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.

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.

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.

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)

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.

* Allow Windows Mobile to correctly load dll's
* Use correct scheme for EAPI on Windows and include config.h when necessary
* add -mwin32 to compiler flags when compiling with cegcc

Although I used 3 lines comments to state it was not required, it is
required because none of the values accounted includes the '\0'.

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.

every thing is not really cleaned on shutdown (It make it crash, if
you shutdown completely the font system and then restart it again).

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.
