* Allow GCC to build Skia on Mac.Gravatar mtklein2014-10-13
| | | | | | | | | | | | | GCC doesn't understand -fasm-blocks or -mpascal-strings, but we don't care about them. While looking around in Gyp, I noticed a better way to disable warnings about offsetof so that it doesn't tell us "disabling this warning makes no sense in C" for every C source file we compile.

* Draw more accurate thick-stroked Beziers (disabled)Gravatar caryclark2014-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Draw thick-stroked Beziers by computing the outset quadratic, measuring the error, and subdividing until the error is within a predetermined limit. To try this CL out, change src/core/SkStroke.h:18 to #define QUAD_STROKE_APPROXIMATION 1 or from the command line: CPPFLAGS="-D QUAD_STROKE_APPROXIMATION=1" ./gyp_skia Here's what's in this CL: bench/BezierBench.cpp : a microbench for examining where the time is going gm/beziers.cpp : random Beziers with various thicknesses gm/smallarc.cpp : a distillation of bug skia:2769 samplecode/SampleRotateCircles.cpp : controls added for error, limit, width src/core/SkStroke.cpp : the new stroke implementation (disabled) tests/StrokerTest.cpp : a stroke torture test that checks normal and extreme values The new stroke algorithm has a tweakable parameter: stroker.setError(1); (SkStrokeRec.cpp:112) The stroke error is the allowable gap between the midpoint of the stroke quadratic and the center Bezier. As the projection from the quadratic approaches the endpoints, the error is decreased proportionally so that it is always inside the quadratic curve. An overview of how this works: - For a given T range of a Bezier, compute the perpendiculars and find the points outset and inset for some radius. - Construct tangents for the quadratic stroke. - If the tangent don't intersect between them (may happen with cubics), subdivide. - If the quadratic stroke end points are close (again, may happen with cubics), draw a line between them. - Compute the quadratic formed by the intersecting tangents. - If the midpoint of the quadratic is close to the midpoint of the Bezier perpendicular, return the quadratic. - If the end of the stroke at the Bezier midpoint doesn't intersect the quad's bounds, subdivide. - Find where the Bezier midpoint ray intersects the quadratic. - If the intersection is too close to the quad's endpoints, subdivide. - If the error is large proportional to the intersection's distance to the quad's endpoints, subdivide.

* Make the Sk GL context class an abstract base classGravatar kkinnunen2014-10-09
| | | | | | | | | | | | | | | | | | | | | | | Make the Sk GL context class, SkGLNativeContext, an abstract base class. Before, it depended on ifdefs to implement the platform dependent polymorphism. Move the logic to subclasses of the various platform implementations. This a step to enable Skia embedders to compile dm and bench_pictures. The concrete goal is to support running these test apps with Chromium command buffer. With this change, Chromium can implement its own version of SkGLNativeContext that uses command buffer, and host the implementation in its own repository. Implements the above by renaming the SkGLContextHelper to SkGLContext and removing the unneeded SkGLNativeContext. Also removes SkGLNativeContext::AutoRestoreContext functionality, it appeared to be unused: no use in Skia code, and no tests.

* BBHs: void* data -> unsigned dataGravatar mtklein2014-10-02
| | | | | | | | | | | | | | Now that the old backend's not using BBHs, we can specialize them for SkRecord's needs. The only thing we really want to store is op index, which should always be small enough to fit into an unsigned (unsigned also helps keep it straight from other ints floating around). This means we'll need half (32-bit) or a quarter (64-bit) the bytes in SkTileGrid, because we don't have to store an extra int for ordering.

* Strip old backend recording down to essentialsGravatar mtklein2014-09-30
| | | | | | | | | | | | | | | | | | | | | | | | | Feature-wise, this removes: 1) BBH support; 2) peephole optimizations; 3) record-time text op specializations; 4) the guarantee that SkPaints are flattened. This deletes the optimizations GM, which only exists to test the peepholes of the old backend. SkRecord optimizations are unit tested, and if that ever fails we can think about adding another GM like this, but they're different enough we'd want to start from scratch anyway. We need to keep the code that plays back the specialized text ops around for a while for compatibility with existing .SKPs that have those ops recorded.

* nanobench: lazily decode bitmaps from SKPsGravatar mtklein2014-09-16
| | | | | | | | | | | | | | | | | | This makes it considerably cheaper to run SKP recording benchmarks, without affecting their measurements and without really affecting SKP playback benchmarks at all. On my machine, running out/Release/nanobench --match skp --config nondrendering drops in run time from 6.7s to 2.5s, and the peak RAM usage drops from 129M to 50M. I'm strongly considering making this lazy decoding the default.
