Ebrahim Byagowi 152000d9c7 [fuzz] Practice variations on font object 2020-02-25 21:16:57 +03:30
Ebrahim Byagowi 036d868913 [draw] Add a fuzzer
Specially checks correctness of the API semantics:
* no move happens when a path is already opened with move-to.
* no path will be left open and close-path will happen at the end of opened paths.
* no path opens with a move-to and will be closed with no length.
* paths start and ending points matches.
* no line/quadratic/cubic command will be issued when no path is started.

Ebrahim Byagowi ff984ed3cd Use multiplication to avoid undefined behaviour per clang
Newer versions of MSVC with /we4146 don't like putting negative sign behind a
unsigned number as https://github.com/harfbuzz/harfbuzz/pull/2069
That however have made https://crbug.com/1050424 this complain:
  src/hb-ot-color-sbix-table.hh:304:28: runtime error: negation of -2147483648 cannot be represented in type 'int';
                                        cast to an unsigned type to negate this value to itself
which apparently can be fixed using this change.

Let's see if this won't make another ubsan complain!

[subset] Raise the bar in new vs old table size
https://crbug.com/oss-fuzz/16740

This is actually an interesting thing that {h,v}mtx allocates as
much as a font pretends to have glyphs but the solution is not
that obvious as regular fonts can have less than actually containing
metrics in their {h,v}mtx. This change raises the bar to consider this
hmtx 4 byte for every glyph case.

Initially we wanted to just find things allocating crazy amount of
memory but having the assert has led to interesting findings also
so let's don't remove the assert and see what we can find elsewhere.

Behdad Esfahbod ec2a5dc859 Use class templates for Null objects
This allows partial-instantiating custom Null object for template Lookup<T>.
Before, this had to be handcoded per instantiation.  Apparently I missed
adding one for AAT::ankr.lookupTable, so it was getting the wrong (generic)
null for Lookup object, which is wrong and unsafe.

[test] Remove not-fixed yet testcases (#1268)
I added them but now that I think, it is a bad idea to have them as
fuzzing bots will find good seeds to tweak in order to find easy new
testcases which causes duplicated issues.

Behdad Esfahbod f39166f0c0 [subset] Remove unused hb_subset_profile_t
We might reintroduce it later, but for now remove, as it was unused.
Some things that should have been in this object (drop_hints, etc)
are already in hb_subset_input_t.  So, for now, keep everything there.
