* miniz support in SkFlate / PDFGravatar mtklein2015-02-26
| | | | | | | | | | | | | | | | | | | | | | | | | - Adds miniz.c v115_r4 (latest release) to third_party. - Merges SkDeflateWStream into SkFlate so including "miniz.c" links without duplicating symbols. The only interesting code change I've made is to remove the line fImpl->fZStream.data_type = Z_BINARY; from SkDeflateWStream::SkDeflateWStream(). miniz doesn't have Z_BINARY defined, and as far as I can tell, both zlib and miniz ignore data_type. We should be able to swap skflate.gyp's dependency between zlib.gyp:zlib and zlib.gyp:miniz at will (except of course on Windows) if we're interested in zlib itself. I've left android framework on its own zlib. I think this all means we can stop defining SK_NO_FLATE on Windows. I'll leave the possible cleanup of SK_NO_FLATE itself for another time. Might be we always want to keep this dependency optional. CQ_EXTRA_TRYBOTS=client.skia:Test-Win8-ShuttleA-HD7770-x86-Debug-Trybot BUG=skia: Review URL: https://codereview.chromium.org/957323003

* Tessellating GPU path renderer.Gravatar senorblanco2015-02-26
| | | | | | | | | | This path renderer converts paths to linear contours, resolves intersections via Bentley-Ottman, implements a trapezoidal decomposition a la Fournier and Montuno to produce triangles, and renders those with a single draw call. It does not currently do antialiasing, so it must be used in conjunction with multisampling. A fair amount of the code is to handle floating point edge cases in intersections. Rather than perform exact computations (which would require arbitrary precision arithmetic), we reconnect the mesh to reflect the intersection points. For example, intersections can occur above the current vertex, and force edges to be merged into the current vertex, requiring a restart of the intersections. Splitting edges for intersections can also force them to merge with formerly-distinct edges in the same polygon, or to violate the ordering of the active edge list, or the active edge state of split edges.

* Clean up ColorRectProc plumbing.Gravatar mtklein2015-02-25
| | | | | | | | | | | | | | | | | | | We've always been using the portable ColorRect32, so we don't need the ColorRectProc plumbing. Furthermore, ColorRect32 doesn't seem to be very important (we're only using it in the opaque case, which our row-by-row procs already specialize for). Remove that too. If we find we want specialization for really narrow rects again, let's put it in blitRect() directly. It's pretty unlikely we're going to get platform-specific speedup for blits to non-contiguous memory. My local SKP comparison is +- 3%... most neutral I've ever seen.

| | | | | | | | | | | | | | | | | | | | Like SkTRacy<T>, TSAN will not complain about these. Unlike SkTRacy<T>, TSAN should not complain about these: SkAtomic<T> are threadsafe. This should fix the races now suppressed in TSAN. As written, the memory barriers we're using in SkPixelRef will be dumb but safe (really, dumbest possible but safest possible). If we see a perf hit, we can follow up by putting Ben and I in a room for a while, thinking about it really hard, and using the minimum-strength safe memory barriers. A refactor that steals a bit from the genID would also still be possible with this approach.
