Ben Wagner a1ca701023 [sfnt] Correct FT_ColorStopIterator documentation.
* include/freetype/ftcolor.h (FT_ColorStopIterator): the user should not
 set `p` to NULL before calling `FT_Get_Colorline_Stops`. `p` and
`num_color_stops` are set by `FT_Get_Paint`. `p` and
`current_color_stop` are updated by `FT_Get_Colorline_Stops`.

Werner Lemberg aee6b94727 * builds/unix/configure.raw: Add option `--with-librsvg`.
Since 'librsvg' is written in Rust, this option allows distributions to
avoid a dependency on the entire Rust toolchain to provide the FreeType demo
programs.

Suggested by Lars Wendler in !156.

Eric Jing 89d5cce58d CMakeLists.txt: Fix `Info.plist` path.
When building a framework using CMake with `add_subdirectory`, CMake must be
able to find `freetype-Info.plist` when configuring the framework
properties.

Fixes #1145.

Ben Wagner 335224beee [sfnt] Fix bounds check in SVG.
The `SVG_DOCUMENT_LIST_MINIMUM_SIZE` macro is non trivial and not
protected by parentheses. As a result, the expression
`table_size - SVG_DOCUMENT_LIST_MINIMUM_SIZE` expands to
`table_size - 2U + SVG_DOCUMENT_RECORD_SIZE` instead of the expected
`table_size - (2U + SVG_DOCUMENT_RECORD_SIZE)`. This causes an incorrect
bounds check which may lead to reading past the end of the `SVG ` table.

* src/sfnt/ttsvg.c (tt_face_load_svg): wrap macro definitions in
parentheses.

Ben Wagner 034e5dbf92 [psaux] Full bounds check for OtherSubr 19.
It is possible for OtherSubr 19 to be invoked when `decoder->buildchar` is
NULL (so that `decoder->len_buildchar` is 0), the `blend` is non-NULL with
`blend->num_designs` set to 2, and the user supplied `idx` to be large (for
example 0xFFFFFFFE).  Since these are all `FT_UInt32` the existing bounds
check overflows in a well defined manner, allowing for an invalid call to
`memcpy`.

In addition, it is possible to call OtherSubr 19 with
`decoder->len_buildchar`, `blend->num_designs`, and `idx` all zero (implying
that `blend->weight_vector` and `decoder->buildchar` are NULL).  This passes
the bounds check (it is logically always fine to copy nothing starting at
index zero) but may invoke undefined behavior in `ft_memcpy` if it is backed
by `memcpy`.  Calling `memcpy` with either the `src` or `dst` NULL is
undefined behavior (even if `count` is zero).

* src/psaux/psintrp.c (cf2_interpT2CharString): Correctly check that
`blend->num_designs` can be copied to `decoder->buildchar[idx]`.
Also avoid passing NULL to `ft_memcpy`.

suzuki toshiya bcdfa38692 [cmake] Drop the support of CMake 2.x.
* CMakeLists.txt: Require CMake 3.0 (released on 2014) or newer.

The issue #1059 reports the difficulty to support both of
CMake 2.x and newer one by single CMakeLists.txt without
the inflation of cmake_policy() workarounds.

For better maintainability, the support of CMake 2.x is
dropped.

Alexei Podtelezhnikov 00ae29fcd2 [pshinter] Tune PSH_STRONG_THRESHOLD_MAXIMUM value.
Before the change, the hinting engine frequently confused horizontal
stem and serif hints making some stems too thin and some serifs too
thick. The value was tuned using serif fonts from the URW+ base 35
collection.

of bits from a larger mask. There is no need to zero unused bits,
already zeroed during allocation.
