Here are the characteristics :
- It uses the original path, before stroking
- It supports traight lines only (no curves)
- It supports butt or square caps only
- It supports miter or bevel joins only
- No AA support
Support for these will be added step by step later on.
A first pass at the benchmarks on my linux machine gave me these approximate speed improvements (running all bench with the option '--forceAA 0') :
path_stroke_small_long_line 4X
path_stroke_small_sawtooth 4X
path_stroke_big_rect 4X
path_stroke_small_rect 6X
path_stroke_big_triangle 4X
path_stroke_small_triangle 10X
lines_1_BW 1.5X
dashline_2_square 1.5X
dashline_1_square 1.5X
Also note that I can't submit this code until GrDrawTarget::isOpaque() is implemented, unless I just disable my renderer completely for now.
BUG=chromium:135111
TEST=The following gms are affected and may require rebaselining : lineclosepath, linepath, strokes_poly

SkBlurImageFilter, sets it on an SkPaint, passes that paint to saveLayer(),
draws the primitives which are to be blurred, then calls restore(), which
applies the blur. The blurs have separate sizes in the horizontal and vertical
direction. This feature is GPU-only for now.
NB: Due to the clipping change, there are slight pixel differences on the
blurs_gpu and shadows_gpu tests, so those will require rebaselining on all
platforms, as will some of the WebKit layout tests (TBD).
