rewrite includes to not need so much -Ifoo Current strategy: everything from the top Things to look at first are the manual changes: - added tools/rewrite_includes.py - removed -Idirectives from BUILD.gn - various compile.sh simplifications - tweak tools/embed_resources.py - update gn/find_headers.py to write paths from the top - update gn/gn_to_bp.py SkUserConfig.h layout so that #include "include/config/SkUserConfig.h" always gets the header we want.

// allows some float values for path points
FuzzPath -> FuzzNicePath This CL renames FuzzPath() to FuzzNicePath() to remind us that it's meant to create paths that a user could reasonably want to create in good faith, to pass to Skia via its API, etc. Then, add fuzz_nice_rect(), and have FuzzNicePath() use that to create its rectangles and use FuzzNiceMatrix() to create its matrices, just like we already use FuzzNiceRRect() to create rounded rectangles and FuzzNicePath() itself to create sub-paths. Using fuzz_nice_rect() should be the fix for the attached bug. Using FuzzNiceMatrix() is by analogy, more preemptive. While we're at it, rename BuildPath to FuzzEvilPath, so the contrast with FuzzNicePath is more clear. Update the assertions that we create a valid path in FuzzNicePath() to tell us where things went wrong if they do.

Make fuzz::next overloads more consistent Some oss-fuzz bugs (like the linked one) would not reproduce in Skia proper due to the fact that there were subtle overloads of the various Fuzz::next() methods in FuzzCanvas.cpp that were pulled in in Skia proper, but not oss-fuzz. This puts all of them in to FuzzCommon.h and makes the matrix and rrect ones opt-in (fuzz_matrix, fuzz_rrect). Additionally, this renames fuzz.cpp -> FuzzMain.cpp so we can properly include Fuzz.cpp in oss-fuzz without having two mains.

Add Dockerfile for building and running local Skia checkout with SwiftShader This also adds a little helper to fuzz that allows us to see what GPU is being targeted. This is the first step in getting a SwiftShader fuzz target.
