* API for Harmony LCD rendering.Alexei Podtelezhnikov2018-04-304-12/+88
| | | | | This introduces `FT_Library_SetLcdGeometry' for setting up arbitrary LCD subpixel geometry including non-striped patterns.
* Formulate Harmony LCD rendering.Alexei Podtelezhnikov2018-04-284-48/+94
| | | | | | | | | | | This generalizes magic outline shifts that make Harmony LCD rendering work in terms of precise two-dimensional RGB subpixel positions. These coordinates are now set in time of the `smooth' module initialization and later used to shift a glyph outline for rendering. FT_RENDER_MODE_LCD and FT_RENDER_MODE_LCD_V use the same coordinates. The letter, however, rotates them before using. The LCD bitmap padding is also calculated using these coordinates. There should be rendering changes resuting from this commit.

| * Another fix for handling invalid format 2 cmaps.Werner Lemberg2018-04-262-1/+14
| | | | | | | | | | | | | | | | | | | | | | Sigh. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=8003 * src/sfnt/ttcmap.c (tt_cmap2_char_next): Adjust condition to avoid an endless loop.
| * [base] Avoid undefined behaviour in lcd filtering code (#53727).Ben Wagner2018-04-242-2/+9
| | | | | | | | | | * src/base/ftlcdfil.c (ft_lcd_filter_fir, _ft_lcd_filter_legacy): Ensure `height > 0'.

| * [base] Fix bitmap emboldening.Alexei Podtelezhnikov2018-04-222-4/+16
| | | | | | | | | | | | | | | | Bug introduced after release 2.8. * src/base/ftbitmap.c (ft_bitmap_assure_buffer): We use `FT_QALLOC_MULT', which doesn't zero out the buffer. Adjust the bitmap copying code to take care of this fact.
| * Revert "[base] Fix bitmap copying where the new pitch is smaller."Werner Lemberg2018-04-222-50/+14
| | | | | | | | This reverts commit c0f1adedcfaad4f7d2fe912ff4b2933845d61d93.

| * Modernize CMake build.Nikolaus Waxweiler2018-04-104-196/+288
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * CMakeLists.txt, builds/cmake/FindHarfBuzz.cmake: Extensive modernization measures. * .gitignore: Add build/, as that's the example directory used in CMakeLists.txt. This brings up the minimum required CMake version to 2.8.12. The installation paths follow the GNU defaults now, e.g. installing on a 64 bit host will place binaries into the lib64/ folder on e.g. Fedora. Symbols are hidden by default (e.g. `-fvisibility=hidden' on GCC). CMake will no longer look for a C++ compiler. Library and .so version now match the Autotools build. Comments in the build file and informational messages now use platform agnostic example commands. ftoption.h and ftconfig.h are written directly without a redundant `-new' copy. External dependencies are expressed as option()s and will turn up as such in cmake-gui. Internal: Properties such as dependencies and include directories are now privately set on the freetype library instead of globally. The CPack definitions have been cleaned up, the `make dist' has been removed. Source packages generated with CPack don't contain Autotools files and aren't used by the maintainters anyway. On Windows, src/base/ftver.rc is compiled to decorate the library with version and copyright information. A pkg-config file is now generated and installed.
