2017-06-22Minor change to AP generation logicJane Liu
Current behavior: Our CPVT_GenerateAP::Generate*AP() functions do not get called as long as the annotation dictionary has an "AP" entry. Problem: We always need the "N" entry in AP dictionary to display an annotation. Even though the spec requires "AP" dictionary to have an "N" entry for normal mode appearance, in case of a malformed pdf with "AP" but without "N" in "AP", we won't be able to display the annotation at all. Fix: Always check if "AP" has "N" entry to decide whether AP needs to be generated. If not, then we still need to generate AP, and add to the AP dictionary under the key "N".

2017-06-20Cleanup tiling and shading patterns in correct orderDan Sinclair
When a Shading is created we have both a ShadingPattern and a ShadingObject. The ShadingPattern is a ref-counted object that is stored in the CPDF_DocPageData. The ShadingObject, when we have a tiling pattern parent, is stored in the CPDF_Form of the tiling pattern. Currently during destruction it is possible for the ShadingPattern to get cleaned up before the ShadingObject which causes the UnownedPtr probe to fire. This CL loops over all patterns and for each Tiling pattern forces the CPDF_Form to get cleared. This then removes the ShadingObject before we remove the ShadingPattern.

2017-06-19Add heuristic for improving text rendering in CPDF_CharPosList::LoadNicolas Pena
This CL uses the following algorithm for improving substitute font spacing (we are assuming the text layout is horizontal): * Calculate PDFWidth, the width that the PDF says the glyph should have. * Calculate FTWidth, the width calculated by freetype for the glyph, using the substitute font that we'll use to render it. Note that some embedded fonts have PDFWidth == FTWidth + 1, so we consider that to be matching widths. * If PDFWidth > FTWidth + 1 , move the x coordinate by the difference / 2 so that the glyph is rendered in a more centered spot and the text looks better. * If PDFWidth < FTWidth, transform the glyph horizontally by PDFWidth / FTWidth so that the glyph gets compressed and does not overlap with surrounding glyphs.
