enable skia gradients, fix bugs
Allow shading to use Skia for some gradients; linear, radial, and coons patch. The corpus uncovered a few gradient-related bugs in the Skia driver which are fixed as well. Fix corpus 11.pdf by ignoring zero area filled paths. PDFium uses CFX_PathData::GetZeroAreaPath() to determine if a path that doesn't enclosing anything should be drawn anyway, and CFX_AggDeviceDriver::GetDriverType() returns 1 so that the empty path is tweaked so that it doesn't draw too often. There are no tests in the corpus that show the utility of this approach; 11.pdf draws correctly if the zero area paths are ignored. Standardize debugging output so that a separate tool can visualize it. R=dsinclair@chromium.org, thestig@chromium.org Review-Url: https://codereview.chromium.org/2530343004
