- when 3 verts are selected ensure the normal is flipped on the side of existing vert normals.
also use the most distant 2 verts to define the tangent.
- when 2 vertices are selected, the normal wasn't aligned with the vert normal.
Instead of having ifdef __GNUC__ all over the headers
to use special compiler's hints use a special file where
all things like this are concentrated.
Makes code easier to follow and allows to manage special
attributes in more efficient way.
Thanks Campbell for review!
the distance checks could get into a feedback loop so that the result depended on the order of verts/edges.
now you can randomize vert/edge/faces and get exactly the same results.
also made some internal improvements,
- used fixed sized arrays (no need to realloc).
- use vertex tag flags rather then a visit-hash.
- remove 'tots' array that did nothing (not sure why it was added).

More use of bool type, necessitating adding inclusion of BLI_utildefines.h, or moving it up in the inclusion order if it was already included, in various places
- storage.c: make some variables only used in bli_builddir local to that
- storage.c: BLI_file_descriptor_size should allow 0 as a valid file descriptor
- path_util.c: make pointers to non-reentrant storage returned from folder routines const, necessitating making variables holding these returned pointers const elsewhere as well
- path_util.c: BLI_string_to_utf8 closes iconv context in case of conversion error
- blf_lang.c: fill_locales routine now has its own "languages" local variable to construct paths (was stealing internal storage belonging to BLI_get_folder before)
The problem is that, when HAVE__BOOL is not defined (as it is the case in scons currently), BLI_utildefines.h defines bool as a standard type. Was using signed char, which makes eg "bool foo = 1024" be false (overflow)! Especially nasty when using bitflags (think we have been lucky to not have worse bugs because of that)!
So changed fallback bool type to unsigned int.
Looks like _Bool is also a type in std (at least with msvc), so the 'typdef bool _Bool;' generates a name collision... Now using _BLI_Bool as placeholder instead.
by Lawrence D'Oliveiro (ldo)
so BKE_utildefines.h allows use of C99's bool type and true/false.
currently scons wont try to use stdbool.h, and works as if its never found.
- use unsigned ints only (where mixing signed/unsigned)
- turn heap_swap into an inline function, add SWAP_TVAL macro to swap values using a temp value as storage.
- added type checking SHIFT3/4 macros
also style cleanup for CTR_Map
