1b8cb52555 Prevent PartialEvaluator_buildFormXObject from failing if the Matrix or BBox contains indirect objects 
This patch fixes yet another instance of bad PDF data, specifically a case where the `BBox` array contains indirect objects (i.e. `Ref`s).

Fixes the missing image in http://www.int.washington.edu/talks/WorkShops/int_08_37W/People/Franz_M/Franz.pdf#page=24. *Note:* There are missing images on a number of the pages in that file.

2564827503 Fix text spacing with vertical fonts (#6387) 
According to the PDF spec 5.3.2, a positive value means in horizontal,
that the next glyph is further to the left (so narrower), and in
vertical that it is further down (so wider).
This change fixes the way PDF.js has interpreted the value.

29a1cdb6a6 Only choose a (3, 1) cmap table for TrueType fonts that have an encoding specified (issue 6410) 
For (1, 0) cmaps, we have two different codepaths depending on whether the font has/hasn't got an encoding. But with (3, 1) cmaps we don't have a good fallback when the encoding is missing, hence this patch changes `readCmapTable` to only choose a (3, 1) cmap table if the font is non-symbolic *and* an encoding exists. Without this, we'll not be able to successfully create a working glyph map for some TrueType fonts with (3, 1) cmap tables.

Fixes 6410.

0fb31a4a9e Fallback in readCmapTable, instead of using error, for TrueType fonts with unsupported cmap formats (bug 1200096) 
Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1200096.

The problematic font has a `format 2` cmap, which we've never supported properly. Prior to PR 2606, we were able to fallback to a working state, despite not having proper support for that cmap format.

Obviously the best/correct solution would be to implement actual support for more cmap formats[1]. However, I'm hoping that a simple patch will be OK for now, given that:
 - `format 2` cmaps seem to be quite rare in practice, since this has been broken for 2.5 years before anyone noticed.
 - Having a simple patch will make potential uplifts a lot easier.

Re: PR 4731.
Since the URL points to the Internet Archive, I think that adding a linked test-case should be OK. (Also, it's difficult to create reduced, or even `unit`, tests that accurately captures the brokenness of real-world PDF files.)

*Please note:* Since this is a `load` test, `makeref`ing won't be needed.

56a43a3181 Make XRef_indexObjects more robust against bad PDF files (issue 5752) 
This patch improves the detection of `xref` in files where it is followed by an arbitrary whitespace character (not just a line-breaking char).
It also adds a check for missing whitespace, e.g. `1 0 obj<<`, to speed up `readToken` for the PDF file in the referenced issue.
Finally, the patch also replaces a bunch of magic numbers with suitably named constants.

Fixes 5752.

Also improves 6243, but there are still issues.

5128603f64 Also check maybeLength when deciding if a stream is empty in Parser_makeFilter (issue 6360) 
The problem with the PDF files in the issue, besides the obviously broken XRef tables which we're able to recover from, is that many/most of the streams have Dictionaries where the `Length` entry is set to `0`. This causes us to return `NullStream`, instead of the appropriate one in `Parser_makeFilter`.

Fixes 6360.

c85fa00d62 fix handling of flags 1-3 in coons shading 
Short story: somebody got lost in two different indices. pi is an index in the stream and is explained on page 198 of the 32000-spec (however 1-based there), and ps is an index to something in PDF.js. I used the code from flag 0 (which works) to understand which is which. It is also important to understand that for flags 1,2 and 3, the stream is always assigned to the same coordinates and colors. What changes is which "old" coordinates and colors are assigned to what is "missing" in the stream. This is why for these flags, the code is identical except for the assignments in the first "row".

c676ecb5a0 Detect scripted auto-print requests 
Fixes #6106

To avoid future regressions, two new unit tests were added:
1. A new PDF based on the report from #6106, which contains an
   OpenAction of type JavaScript and a string "this.print({...}".
2. An existing PDF from https://bugzil.la/1001080 (from #4698).

Although it does not matter, since we don't execute the JavaScript code,
I have also changed "print(true)" to "print({})" since the print method
takes an object (not a boolean). See "Printing PDF documents", page 62:

e211c25f06 Improve robustness of stream parser (invalid length) 
When the parser finds a stream, it retrieves the Length from the stream
dictionary and advances the lexer to the offset as specified in Length.
If this Length is incorrect, the lexer could end up anywhere.

When the lexer gets in an invalid state, it could throw errors. For
example, in issue 6108, the lexer ends up inside the stream data. This
stream has the ASCIIHexDecode filter, so all characters are made up from
ASCII characters, and the lexer interprets it as a command token. Tokens
cannot be longer than 127 bytes, so eventually 128 bytes are consumed
and the lexer throws "Command token too long" error.

Another possible error is "Illegal character: 41" when the lexer happens
to end up at a ')' due to the length mismatch.

These problems are solved by catching lexer errors and recovering the
parser via the existing stream length detection branch.

fd29bb0c57 Subtract start offset for xrefs in recovery mode 
Xref offsets are relative to the start of the PDF data, not to the start
of the PDF file. This is clear if you look at the other code:

- In the XRef's readXRefTable and processXRefTable methods of XRef, the
  offset of a xref entry is set to the bytes as given by a PDF file.
  These values are always relative to the start of the PDF file (%PDF-).

- The XRef's readXRef method adds the start offset of the stream to
  Xref entry's offset: "stream.pos = startXRef + stream.start".
  Clearly, this line assumes that the entry offset excludes the start
  offset.

However, when the PDF is parsed in recovery mode, the xref table is
filled with entries whose offset is relative to the start of the stream
rather than the PDF file. This is incorrect, and the fix is to subtract
the start offset of the stream from the entry's byte offset.

The manually created PDF file serves as a regression test. It is a valid
PDF, except:
- The integer to point to the start of the xref table and the %%EOF
  trailer are missing. This will activate recovery mode in PDF.js
- Some junk was added before the start of the PDF file. This exposes the
  bad offset bug.

fda858ae33 Don't map glyphs to certain problematic General Punctuation Unicode locations (bug 911034)

2b1a13ba28 Don't map glyphs to Unicode position 0x0E33, i.e. Thai character SARA AM (bug1046314) 
*A similar approach as in PR 5705.*

Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1046314.

According to https://dxr.mozilla.org/mozilla-central/source/gfx/harfbuzz/src/hb-ot-shape-complex-thai.cc#270-365, `0x0E33` is treated as a special case (by the font shaping code in Firefox). Hence it seems reasonable to skip it when adjusting the font mapping.

d8b905048b Add fallback for non-embedded "Century Gothic" CIDFontType2 font (issue 4722 and bug 879561) 
According to practical experiments, falling back to "Helvetica" when we encounter a non-embedded "[Century Gothic](http://en.wikipedia.org/wiki/Century_Gothic)" `CIDFontType2` font seems to work well.
(Also, the section on Wikipedia about "Printer ink usage" *might* provide some anecdotal evidence that Century Gothic is a fairly standard sans-serif font.)

Obviously this patch doesn't make "Century Gothic" fonts render perfectly, as is often the case with non-embedded fonts, but all the text is now legible in the referenced issues.

Fixes 4722.
