2015-10-09Various changes to JBig2 cache:David Lattimore
- Makes the cache be per-document - Keys the cache on ObjNum and stream offset instead of keying on a pointer to the data (which can result in false cache hits). - Makes it so the cache is only used for the globals stream. - Reenable the cache.

2015-10-05Original patch by forshaw.Tom Sepez
Added a fallback Win32 font information class for win32k lockdown. This is to support running PDFIUM within the Win32k lockdown by removing dependancies on USER32/GDI for the font information code. It falls back to using a freetype/directory enumeration implementation if it detects the win32k system calls have been disabled by policy.

This reverts commit 9bd18183ba8210c91d71c3060146235750a4c71c.
2015-09-25Fix the issue that pdfium swallows 'fi' or 'ff' in some pdf filesJun Fang
Pdfium swallows 'fi' or 'ff' in some tested files because it doesn't load the embedded font file correctly. The root cause is that there is incorrect keyword like 'ngendstream' in the stream of the embedded font file. Pdfium tries to find another correct keyword but uses wrong offset rather than accumulated offset.

2015-08-05Early object closing in PDF via premature 'endobj' keywordJUN FANG
Adobe acrobat defines keywords "\nendstream\n" and "\nendobj\n" in object's stream. However, Pdfium searches "endstream" and "endobj" as the keywords in the streams of objects. Some words like "(endstream)" are wrongly treated as keywords in pdfium. This fix follows Adobe's solution. BUG=493126 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1219133005 .
2015-08-05Remove the unused IFX_StreamRead::SetRange() mechanism.Tom Sepez

2015-08-05FPDF_Creator can only create file through embedder-supplied callback.Tom Sepez
Hence, some of the routines taking filename strings are unused. This, in turn allows us to get rid of some other fopen-ishy looking things inside the library. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1264423003 .

FX_HFILE, and the routines that operate on it, are unused. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1259123008 .
2015-07-31Kill IFX_FontMapperTom Sepez
The design envisioned two kinds of font mappers: internal (of type CFX_FontMapper), and external, both of which implement a common interface. But there isn't any means of making an external one, so the interface is redundant. IFX_FontMapper also appears in an apple-specific struct, but was never non-null or used in any way. The CFX_FontMapper class provides its own mechanism to include platform-specific features, as it turns out. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1259123005 .
