Ben Wagner f7daf9d293 [stream] Fix reading s32 when long is s64
`FT_READ_LONG`, `FT_GET_LONG`, and related macros did not return
negative values when `long` is more than 32 bits. `FT_Stream_ReadULong`
would read four bytes into the LSB of an `FT_ULong` and return that.
Since this can never set the MSb of the `FT_ULong` when `FT_ULong` is
more than 32 bits the cast to `FT_Long` never resulted in a negative
value.

Fix this by modifying `FT_Stream_Read*` to return a type of the same
size as the bytes it is reading and changing the `FT_READ_*` and
`FT_GET_*` macros to cast to the same type returned by `FT_Stream_Read*`
but with the correctly signed type (instead of casting to what is
assumed to be the type of `var` which will happen automatically anyway).

There exist a few cases like with the `OFF3` variants where there isn't
generally a type with the correct size. `FT_PEEK_OFF3` works around this
loading the bytes into the three most significant bits and then doing a
signed shift down. `FT_NEXT_OFF3` also already worked correctly by
casting this signed value to another signed type. `FT_Stream_GetUOffset`
works correctly but one must be careful not to attempt to cast the
returned value to a signed type. Fortunately there is only
`FT_GET_UOFF3` and no `FT_GET_OFF3`.

All of these cases are handled correctly when reading values through
`FT_Stream_ReadFields` since it generically computes the signed value
through an `FT_Int32`. This change is essentially doing the same for
these macros.

* include/freetype/internal/ftstream.h (FT_NEXT_*, FT_GET_*, FT_READ*):
Update macros and return types to use fixed size types for fixed size
values.

* src/base/ftstream.c (FT_StreamGet*, FT_StreamRead*): Dito.

Ben Wagner e34a860a07 Document `FT_Outline_Decompose` degenerate segments.
`FT_Outline_Decompose` does not filter out and can return degenerate
segments in an outline. This can be surprising when attemping to
stroke such an outline. Clarify the existing documentation on this
matter to cover all forms of degeneracy (without specifying exactly
how they will be reported), why they might arise, and better explain in
what cases they may be an issue.

Alexei Podtelezhnikov 054782c48e [base] Undefined scale means no scale.
It might be surprising that FreeType does not have default ppem and
the size has to be set explicitly or face undefined behavior with
undefined variables and errors. This offers an alternative to
missing or zero scale by simply setting FT_LOAD_NO_SCALE.  Defined
behavior is bettr than undefined one.

This is alternative to !132 and discussed in

Werner Lemberg 9079c5d91a Provide C++ versions for public macros with casts.
Many FreeType clients use C++.  However `g++ -Wold-style-cast` warns for
macros with C-style casts even for system header files; this also affects
directories included with `-isystem`.  While this could be seen as a problem
with g++, the problem is more a philosophical one: Over the time, C and C++
diverged more and more, and some features of C are no longer the 'right'
solution in C++.

Ben Wagner c71eb22dde Fix typos in memory macros.
FT_QNEW_ARRAY and FT_QRENEW_ARRAY were using the non-Q
FT_MEM_NEW_ARRAY and FT_MEM_RENEW_ARRAY. Change these to use the Q
versions. Also fix the one issue discovered in tt_face_load_name
where table->names is created with FT_QNEW_ARRAY but the extra
string member is not initialized to NULL.

* include/freetype/internal/ftmemory.h (FT_Q(RE)NEW_ARRAY):
Use FT_MEM_Q(RE)NEW_ARRAY as needed.

* src/sfnt/ttload.c (tt_face_load_name): Initialize `entry->string`.
