Current strategy: everything from the top
Things to look at first are the manual changes:
- added tools/rewrite_includes.py
- removed -Idirectives from BUILD.gn
- various compile.sh simplifications
- tweak tools/embed_resources.py
- update gn/find_headers.py to write paths from the top
- update gn/gn_to_bp.py SkUserConfig.h layout
so that #include "include/config/SkUserConfig.h" always
gets the header we want.
No-Presubmit: true

* SkCachedData behaves differently (regarding its locked/unlocked state) depending on
|
|
* when it is in the cache or not. Being in the cache is signaled by calling attachToCacheAndRef()
|
|
* instead of ref(). (and balanced by detachFromCacheAndUnref).
|
|
*
|
|
* Thus, among other things, we test the end-of-life behavior when the client is the last owner
|
|
* and when the cache is.
