* SkPDF: unify drawText and drawPosTextGravatar halcanary2016-08-15
| | | | | | | | | | | | Motivation: a later CL will add drawTextBlob() (after https://crrev.com/2084533004 lands). This CL is designed with that change in mind. Also fewer redundant lines of code.

* SkPDF: Subset Type3 (fallback) fontGravatar halcanary2016-08-12
| | | | | | | | | | | | | | | | | | | Motivation: significant file-size reduction. Also: SkPDFFont::subsetFont() returns a sk_sp<SkPDFObject> rather than a SkPDFFont*. SkPDFType3Font constructor no longer populates font info; relies on subsetting. SkPDFFont::Create is easier to read Also: SkPDFType3Font are scaled by emSize rather than 1000.

Expose `SkPDFAppendCmapSections()` for testing. SkPDFFontImpl.h - Fold into SkPDFFont.

| | | | | | | | | | | | | | | SkPDFFont: - never request kHAdvance_PerGlyphInfo from typeface. - set_glyph_widths() fn uses a glyph cache to get advances. - stop expecting vertical advances that are never requested. - composeAdvanceData() now non-templated - appendAdvance() one-line function removed SkPDFDevice: - use a glyph cache for getting repeated advances.

| | | | | | | | | | | | | | | | | | | | Instead of having a fFontGlyphUsage on each device and one on each document, just have the one on the document, and never merge. Make fGlyphUsage accesible on SkPDFDocument. Remove SkPDFGlyphSetMap::merge, ::reset, and SkPDFGlyphSet::merge. SkPDFGlyphSetMap has an TArray of SkPDFGlyphSet, not TDArray of SkPDFGlyphSet pointers. SkPDFGlyphSet and SkPDFBitset get move constructors. All tests produce exactly identical output PDFs.

Second half moved to onClose. create_pdf_page function removed: Merged into onEndPage. generate_page_tree: Refactored to use SkTArray<sk_sp<T>> over SkTDArray<T*>. (the former is explicit about ownership, the latter is unclear.) No longer populates a structure of objects to be dumped, unnecessary since dump is always called after serialization. Takes ownership of fPages and returns root of tree-ified version. Less reference churn. SkPDFGlyphSetMap: use new-style iterator.

In Debug mode, assert that each object is emited exactly once by asserting that emitObject is never called after drop(). Same for addResources(). To make sure that top level objects don't get deleted prematurely, SkPDFObjNumMap takes a reference. Motivation: save RAM. Allow even earlier serialization with later changes. Also: Switch some SkTDArrays to SkTArrays.

* detach -> releaseGravatar mtklein2016-03-16
| | | | | | | | | | | | | The C++ standard library uses the name "release" for the operation we call "detach". Rewriting each "detach(" to "release(" brings us a step closer to using standard library types directly (e.g. std::unique_ptr instead of SkAutoTDelete). This was a fairly blind transformation. There may have been unintentional conversions in here, but it's probably for the best to have everything uniformly say "release".
