A
angle
Commit b1eeba1f by Jamie Madill Committed by Commit Bot
Options

Use a C API for the ANGLE platform.

The main purpose of this change is to fix a fuzzer bug where we would trigger undefined behaviour calling between Chrome and ANGLE. It's not specced how virtual function calls work if the shared objects are not directly linked together, and ANGLE and Chrome are not linked. Replace the old class-style API with a C dispatch table. Follow-up work will make the Platform owned by the Display instead of using global variables, but fixing this is a bit tricky.
