commit-bot@chromium.org 5e00989a28 Add SkPDFDeviceFlatenner which extends SkPDFDevice to add support to flatten the path and the text when we have perspective.
prepare to deprecate SkPDFDevice constructor, and route gm and render_pdfs to use SkDocument::Create pdf interface instead. - controlled by a flag
add comments where we are supposed to flatten other features (paint, shaders, ... )
