SharedSolver was archiving too many constraints, partly because of
multiple typos, also because it archived some which were just artifacts
of the layout process. These extra constraints are created when the
layout calls SetRange() on the left/top/right/bottom tabs during layout.
* LinearSpec/ActiveSetSolver had to be adjusted to get access to the
constraints added by the SetRange() calls.
* BALM::TabBase was adjusted to avoid a segfault during unarchiving,
caused by an unitialized member.
* ALMFriendLayoutTest was adjusted to include a more obvious custom
constraint for testing.
Also make ALMGroup totally self-contained, i.e. BALMLayout no longer
does the parsing, and is completely unaware of ALMGroup. A small touch
of refactoring as well.
* allow for independent left, top, right and bottom insets
* allow for independent vertical and horizontal spacing between tabs
* allow for the usage of Haiku's spacing constants such as B_USE_WINDOW_INSETS
The gcc2 cross-compiler built on Mac OS X Lion has a bug in it
where it is erroring with 'cast specifies signature type' when
assigning 0 or NULL to a pointer to a member fuction. NULL in this
instance is correctly converted to 0 since it is illegal to assign
((void*)0) to a pointer to a member function. However, it should
be legal to assign 0 to a pointer to a member function. Thus, there
is a bug. Since I can't fix the gcc2 compiler I am working around
this bug by assigning the pointer to a do nothing function instead.
My host compiler version is
i686-apple-darwin11-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5666) (dot 3)
The same error occurs using the default gcc-llvm compiler and
a standard gcc 4.61 built from source. This bug does not occur on
Mac OS X 10.6 gcc2 or gcc4, nor does it occur on Mac OS X 10.7 with
the gcc4 cross-compiler.
If and when we decide to finally leave gcc2 behind we can revert this
change.
* added optional feature package for freetype 2.4.6 gcc4/gcc2 x86 and gcc4 ppc.
* FT_CONFIG_OPTION_SUBPIXEL_RENDERING is disabled, --include-patented-code doesn't
change this setting anymore. This would require different packages.
* drop freetype sources and headers from the tree.
* fix decorators, test app server and appearance to use feature package headers.
* hybrid build untested.
