Behdad Esfahbod 4020c6b286 m[blob] An empty blob can always be made writable 2021-02-19 18:40:48 -07:00
Behdad Esfahbod 2d39031f7b [buffer/set/map] Move immutable check only to C API boundary 
The immutable objects are a concept only enforced by the C API.
So move checks only to that region.

This does assume that the rest of the code is careful not getting
into these internal methods on immutable objects, which something
we do, but have no way of enforcing (currently).

Behdad Esfahbod 7b8a8adb7d [aat] Fix unsafe-to-break marking when end-of-text action kicks in 
The state we are dealing with here is the previous state; so it should
cause unsafe_to_break before current glyph.

I'm surprised this wasn't caught by any tests. Guess we don't have any
fonts with fancy end-of-text forms.

Behdad Esfahbod 505b3fc6cf [harfbuzz.cc] Fix OffsetTable name clash with Mac headers 
There's no easy way to undo a "using namespace" in our sources, so by the time
we get to include hb-coretext.cc from harfbuzz.cc, we already have "using namespace OT"
active, which clashes with Mac headers.

Error was:

It was caught by the CI build in the PR, but apparently we are now used

Also, yay for multiple build systems.
