This reverts commit32a4910e57. Reason for revert: SkMatrix::toString use has been removed from flutter and has been picked up in fuchsia Additionally some bookmaker changes take into account recent additions of typedef comments and the generated header comment. Original change's description: > Revert "remove toString" > > This reverts commit5191880cbf. > > Reason for revert: broke flutter > > Original change's description: > > remove toString > > > > toString may have been used by obsolete debugger only > > find out if that is so > > > > R=​brianosman@google.com,bsalomon@google.com > > > > Docs-Preview: https://skia.org/?cl=119894 > > Bug:830651 > > Change-Id: I737f19b7d3fbc869bea2f443fa3b5ed7c1393ffd > > Reviewed-on: https://skia-review.googlesource.com/119894 > > Commit-Queue: Cary Clark <caryclark@google.com> > > Reviewed-by: Brian Salomon <bsalomon@google.com> > > TBR=bsalomon@google.com,brianosman@google.com,caryclark@google.com,caryclark@skia.org > > Change-Id: I9f81de6c3615ee0608bcea9081b77239b4b8816c TBR=bsalomon@google.com,brianosman@google.com # Not skipping CQ checks because original CL landed > 1 day ago.
