This is step one: - make SkXfermode useless to public clients - everything they should need is in SkBlendMode.h Step two: - remove SkXfermode.h entirely (since skia core will already be using SkXfermodePriv.h) BUG=skia: GOLD_TRYBOT_URL= https://gold.skia.org/search?issue=4534 Change-Id: If2cea9f71df92430ed6644edb98dd306c5572cbc Reviewed-on: https://skia-review.googlesource.com/4534 Commit-Queue: Mike Reed <reed@google.com> Reviewed-by: Florin Malita <fmalita@chromium.org>
