This should allow clients to include Skia and their vulkan files in any order. However, it does require that when clients are building their files that include skia with vulkan, they must have vulkan/vulkan_core.h on their include path somewhere. Bug: skia: Change-Id: I969db396c92127be7c8df754926d175f38b8aafa Reviewed-on: https://skia-review.googlesource.com/c/172147 Reviewed-by: Brian Salomon <bsalomon@google.com> Commit-Queue: Greg Daniel <egdaniel@google.com>
