2016-12-06re-enable skia cachingchromium/2944caryclark
This permits consecutive path drawing or text drawing to combine if their graphics state matches. This speeds up rendering considerably when PDFium draws in many small parts. It also allows discarding changes to the clip state that have no effect from draw to draw. All corpus tests draw equivalently with caching enabled or disabled. Change the member order in CPDF_PageRenderContext so the device is flushed before the referencing annotation is deleted. Add more printf style debugging for test draws.

2016-12-05enable skia gradients, fix bugscaryclark
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

Reasoning: the pTextAdvanceX in CPDF_TextObject::CalcPositionData is being multiplied by horz_scale in CPDF_TextObject::CalcPositionData. Then, m_pCurStates->m_TextX is updated by this amount.

2016-11-23fix negative font sizecaryclark
PDF can specify a negative font size to change the y-axis for text. Add support in the Skia driver for that. The cached form for text and paths had fallen out of sync with the uncached code used by skiapaths, so sync that up so that the mainline skia setting has those bug fixes as well. This does not fix the underlying bug in 528103, but gets Skia on parity with native PDFium text rendering. The bold text is still drawn in the wrong place.
