This makes the code reflect what is actually going on. During DDL recording the SkGpuDevice only holds a recording context. This can't land until the following Chrome-side CL lands: https://chromium-review.googlesource.com/c/chromium/src/+/2277964 (Add GrContext.h include to skia renderer for upcoming Skia roll) Reviewed-on: https://skia-review.googlesource.com/c/skia/+/299867 Commit-Queue: Robert Phillips <robertphillips@google.com> Reviewed-by: Brian Salomon <bsalomon@google.com> Reviewed-by: Adlai Holler <adlai@google.com> Change-Id: I6ef3896f5a270a4fa7af37f9121f68a66653cce2 Reviewed-on: https://skia-review.googlesource.com/c/skia/+/300896
