Implement SkAndroidFrameworkUtil::getBaseWrappedCanvas, which gets the real canvas behind SkPaintFilterCanvas. This is useful, because SkCanvas::drawDrawable works differently on a GPU backed canvas. Test: Built and ran with Android Bug: b/128792554 Change-Id: I5b75d42256d7a4efca987d55be2ce064c10fb4e7 Reviewed-on: https://skia-review.googlesource.com/c/skia/+/204442 Commit-Queue: Stan Iliev <stani@google.com> Reviewed-by: Florin Malita <fmalita@chromium.org>
