SkPDF: Refactor PDFShader to use ShTHashMap<> my tests run ~14% faster. - Split out gradient shaders from image shaders. new compilation unit: SkPDFGradientShader - Common functions InverseTransformBBox and PopulateTilingPatternDict moved to SkPDFUtils - Split SkPDFShader::State into image and gradient structures. - SkPDFCanon is now a simpler structure, with no logic of its own. I am considering just moving all of its fields into SkPDFDocument - SkPDFShader::State (the image/fallback shader) now is POD, making the use of a hashmap for canonicalization straightforward. Formerly, we used a linear search. - Do not bother trying to canonicalize the falback image shader. - SkPDFGradientShader::Key is not POD; comparison of two objects requires looking at the contents of two variable-sized arrays. We now pre-calculate the hash of the arrays using SkOpts::hash and store a hash for the object in the fHash field. Using that hash, we can now canonicalize using a hashmap instead of a linar search! - several static functions renamed to follow style guidelines - stop using codeFunction function pointer; I find that less clear than it could be. - operator==() for SkPDFShader::State and SkPDFGradientShader::Key is now much simpler and can now be inlined. - SkArrayEqual template in SkPDFUtils.h No change to PDF output.
