I pushed it with a slightly different commit message:

commit 44a07a66135c4f534c909bd84f24cf7c0275a914

    quartz: Never acquire recording surfaces

    We need to replay if the source/mask surface is a recording surface
    otherwise, a crash happens if it is unbounded.

    Fixes crashes in recordxx-xxx tests

I also pushed the one for transforming clip paths and another patch to
respect the scaling when replaying recording surfaces in quartz.
