1f5a54c768 [gvar] fix infinite loop introduced by 11f3fca 
The attempt on removing end_points had made the code unreadable
and has intrdouced infinite, fixed by making the code clear what
it tries to achieve.

346ab9884b [gvar] Return gracefully even if coords_count != gvar's axis count 
It shouldn't be that common to have the situation, even so, no need to
reject entire a glyph even if gvar isn't used.

5f23a76e99 [cff] Don't remove coords const qualification 
We should find some way to audit all the const removals, perhaps by
enabling -Wold-style-cast warning on the project and turning all the
implicit const removals to const_cast.

da37880e17 [draw] Add a private bit field instead null-checking quad-to callback 
This doesn't imply the the design is good or stable just is better
to not fail due to null quad-to callback so as our quad-cubic curves
translation is currently table limited which can be revisited anytime.

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!
