assume that it ends with a new line.

Michiharu Ariza 76e54d2bd8 fixed subroutinized CFF2 flattening 
and some code cleanup
 2018-09-21 12:16:36 -07:00
Michiharu Ariza 321e592333 Added desubroutinize option to generate-expected-outputs.py 
Currently hb-subset always desubroutinizes CFF fonts.
Note that even with this option fonttools won't generate the expected subset CFF fonts. They were manually created & tweaked to match hb-subset output.
 2018-09-20 10:31:06 -07:00
Michiharu Ariza f212c050ad Added VORG struct and its subsetter 
new file: hb-ot-vorg-table.hh

Behdad Esfahbod dc8ed45292 [morx] Implement forward/backward processing 
We reverse too many times. Can be optimized. But I doubt many fonts
use reverse lookups, so doesn't matter.

Other than not applying user features, this completes morx table
implementation.

Behdad Esfahbod 041a08de3d [morx] Improve buffer position in Insertion w DontAdvance and wo 
Just speculation. Needs tests to determine which is correct behavior.

Michiharu Ariza ebeccf3e63 fixed char widths & standard Encoding in subset CFF 
also merged flush_n_args to flush_args into one
takes start index of the arguments on stack instead of count
 2018-09-18 17:24:30 -07:00
Michiharu Ariza bf4eb2e4cf Added SourceSansPro-Regular along as CFF full-font test case 
derived "expected" subset fonts from fonttools then manually tweaked further so they resemble hb-subset output
 2018-09-18 15:53:37 -07:00
Michiharu Ariza e75e7224c9 include curve control points in extents 
this makes results consistent with FT
also optimized handling of path end points

Simon Hausmann 6a97d0f3d3 Fix installation of cmake config when building with cmake (#1161) 
When building with the auto tools, the manually mantained
harfbuzz-config.cmake is installed. When building with cmake, we can use
cmake to generate the correct config files for us and install them.

Behdad Esfahbod 606bf57430 Revert forcing use of single-parameter static_assert() 
Some clang versions define static_assert as a macro apparently, so we cannot
redefine it...

This reverts commit 94bfea0ce6.
This reverts commit 4e62627831.

Behdad Esfahbod 10642b3fbf Disallow null-enabled offsets to unsized structures... 
...like UnsizedArrayOf<>.

This fixes a class of crasher bugs, mostly with color and AAT tables.  We
cannot use nullable offsets to varsized data that does not declare min_size,
because it's nost safe to use our fixed-size null pool for types that have
their size external.  So, use non_null'able offsets for these.

A further enhancement would be to make use of min_size in Null<> itself.
Will try that after.

Behdad Esfahbod 9ff76c6025 [morx] Respect default feature settings

correct subtables.

Behdad Esfahbod f8ccb545c4 [dfont] Disable null-processsing for offsets 
An offset to unsized arrayis not safe to be redirected to our fixed-sized
null pool.  Plus, we want to reject, not repair, bad-looking dfonts.
