456ad438d8 Issue a warning instead of an error for long Names 
The PDF specification (cited below) specifies a maximum length of a name
in bytes as a minimal architectural limit. This means that PDF *writers*
should not create names that exceed 127 bytes.

It does not forbid PDF *readers* to accept such names though. These
names are only used internally to link PDF objects to other objects. For
these use cases, the lengths of the names do not really matter. Hence I
have changed the implementation to not treat long names as errors, but
warnings.

> (7.3.5) The length of a name shall be subject to an implementation
> limit; see Annex C.
>
> (Annex C.2) Table C.1 describes the minimum architectural limits that
> should be accommodated by conforming readers running on 32-bit
> machines. Because conforming readers may be subject to these limits,
> conforming writers producing PDF files should remain within them.
>
> (Table C.1) name 127 "Maximum length of a name, in bytes."

7df78f997e Slightly more efficient getDestination 
For named destinations that are contained in a `Dict`, as opposed to a `NameTree`, we currently iterate through the *entire* dictionary just to fetch *one* destination.
This code appears to simply have been copy-pasted from the `get destinations` method, but in its current form it's quite unnecessary/inefficient since can just get the required destination directly instead.

940bedf75f Add a unit-test that attempts to fetch a non-existent named destination 
Doing this helped uncover an issue with the `getDestination` implementation.
Currently if a named destination doesn't exist, the method (in `obj.js`) may return `undefined` which leads to the promise being stuck in a pending state.
*Note:* returning `null` for this case is consistent with other methods, e.g. `getOutline` and `getAttachments`.

bc865b9e2d Ensure that we fetch all indirect objects (i.e. |Ref|s) in ColorSpace_parseToIR 
Recently I've landed a number patches which fixed issues with ColorSpaces. In most of these cases the cause of the failures were, either partially or entirely, related to the fact that we didn't resolve indirect objects (i.e. the code was missing `xref.fetchIfRef(...)`).

The purpose of this patch is to fix the few remaining cases where indirect objects *could* potentially cause failures.
Given that we have seen how this causes failures in practice, I thus think that it makes sense to try and avoid further issues, instead of waiting for users to file even more bugs for this part of the code-base.

a64536901a Increase the font weight used for non-embedded ArialBlack fonts 
Currently non-embedded ArialBlack fonts are not rendered bold enough, compared to e.g. Adobe Reader.
The issue is that we set the font weight to `bolder`, but since that is actually relative to the font weight of the parent, the result is that there's no practical difference from just using `bold`.

This patch attempts to address that, by explicitly setting the font weight to the maximum value instead (see https://developer.mozilla.org/en-US/docs/Web/CSS/font-weight).

*Note:* I expect one test "failure" in `issue5801`, which in this case is an improvement, since that PDF file uses ArialBlack.

6f2f0700b7 Don't map glyphs to certain problematic Thai/Lao Unicode locations (issue 5994) 
*This patch depends on PR 5990.*

According to https://dxr.mozilla.org/mozilla-central/source/gfx/harfbuzz/src/hb-ot-shape-fallback.cc#38, certain Thai/Lao characters are treated as special by the font shaping code in Firefox.
Further down in that file, https://dxr.mozilla.org/mozilla-central/source/gfx/harfbuzz/src/hb-ot-shape-fallback.cc#216, the vertical position of glyphs is modified, which should thus explain why some glyphs end up in the wrong position in the PDF file.

4c9b65f0e1 Extract correct PDF format version from the catalog 
The 'Version' field of the most recent document catalog, if present, is
intended to supersede the value in the file prologue.

This is significant for incrementally-built PDF documents and generators that
emit a low version in the prologue and later apply a format version based on
PDF features used, such as Apple's CoreGraphics/Quartz PDF backend.

Fixes the internal version variable, as well as the PDFFormatVersion reported
by the API and consumed by viewers.

f19a1db414 Create a IdentityToUnicodeMap in evaluator.js when toUnicode contains IdentityH/IdentityV 
Currently if a font contains a `toUnicode` entry, we always create a new `ToUnicodeMap` in evaluator.js. This is done even for `IdentityV/IdentityH`, despite to possibility to use the much more compact `IdentityToUnicodeMap` representation.
This patch refactors the `IdentityH/IdentityV` cases, to:
 - Avoid calling `IdentityCMap.getMap`, since this prevents allocating and iterating through an array with 65536 elements.

 - Ensure that the handling of `toUnicode` is actually correct in fonts.js.
We rely on `toUnicode instanceof IdentityToUnicodeMap` in a few places, and currently this does not work correctly for `IdentityH/IdentityV`.

979635138a Improves rendering performance of annotation layers. 
This change does the following:
 * Address TODO to remove getEmptyContainer helper.
 * Not set container bg-color. The old code is incorrect, causing it to
   not have any effect. It sets color to an array (item.color) rather
   css string. Also in most cases it would set it to black background
   which is incorrect.
 * only add border instructions when there is actually a border
 * reduce memory consumption by not creating new 3 element arrays for
   annotation colors. In fact according to spec, this would be incorrect,
   as the default should be "transparent" for an empty array. Adobe
   Reader interprets a missing color array as black however.

Note that only Link annotations were actually setting a border style and
color. While Text annotations might have calculated a border they did
not color it. This behaviour is now controlled by the boolean flag.

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.

(This may be overkill)
- Some documents we encountered have invalid xref ids, which were
always coming out as ‘0000000000000000’ - so we detect that and use the
MD5 instead.

96a77e9d6a Add basic support for non-embedded Wingdings fonts 
This is a tentative patch that adds *very* basic support for non-embedded Wingdings fonts (a Windows version of Dingbats), by falling back to the ZapfDingbats encoding. Obviously this approach will not work perfectly, but in my opinion it seems to work reasonably well in pratice.

Instead of this very simple patch, another option would be to try and include more complete glyph data for Wingdings, e.g. a Unicode map and glyph widths, similar to what was done for ZapfDingbats.
However there is, in my opinion, one important difference between Wingdings and ZapfDingbats: ZapfDingbats is part of the 14 standard fonts, which in previous versions of the PDF specification was assumed to be available in PDF readers. To improve compatibility with older files, it thus makes sense for us to include data for ZapfDingbats.
However Wingdings has never been a standard font in PDF files, hence PDF files using it *should* thus contain all the necessary font data.

Given the above, I thus believe that it should be OK to fall back to ZapfDingbats for now. If non-embedded Wingdings fonts turns out to be *a lot* more common, then we can revisit this later.

Fixes 4301 completely.
Fixes 4837 almost completely. With this patch the bullets are displayed correctly, but the arrows are not of the correct type.
Fixes `artofwar.pdf`, pages 14 and 15.

970c048d50 fixes caching of inline images during parsing. 
As described in #5444, the evaluator will perform identity checking of
paintImageMaskXObjects to decide if it can use
paintImageMaskXObjectRepeat instead of paintImageMaskXObjectGroup.

This can only ever work if the entry is a cache hit. However the
previous caching implementation was doing a lazy caching, which would
only consider a image cache worthy if it is repeated.
Only then the repeated instance would be cached.
As a result of this the sequence of identical images A1 A2 A3 A4 would
be seen as A1 A2 A2 A2 by the evaluator, which prevents using the
"repeat" optimization. Also only the last encountered image is cached,
so A1 B1 A2 B2, would stay A1 B1 A2 B2.

The new implementation drops the "lazy" init of the cache. The threshold
for enabling an image to be cached is rather small, so the potential waste
in storage and adler32 calculation is rather low. It also caches any
eligible image by its adler32.

The two example from above would now be A1 A1 A1 A1 and A1 B1 A1 B1
which not only saves temporary storage, but also prevents computing
identical masks over and over again (which is the main performance impact
of #2618)

ca027ebfdb Fix the exception propagation when rejecting workerReadyCapability 
Currently when an exception is thrown, we try to reject `workerReadyCapability` with multiple arguments in src/core/api.js. This obviously doesn't work, hence this patch changes that to instead reject with the exception object as is.
In src/core/worker.js the exception is currently (unncessarily) wrapped in an object, so this patch also simplifies that to directly send the exception object instead.

The scanned, black-and-white document at

the critical GRAYSCALE_1BPP optimization because the optimization is
skipped if `needsDecode` is set.

This change addresses that, and reduces both rendering time and memory
usage for that document by almost 10x.

9674abc542 Ignore setGState no-ops. 
For the document in #2504, 11% of the ops are `setGState` with a
`gStateObj` that is an empty array, which is a no-op. This is possible
because we ignore various setGState keys (OP, OPM, BG, etc).

This change prevents these ops from being inserted into the operator
list.

ffae848f4e Reduce ASCII checks in makeInlineImage(). 
makeInlineImage() has a "are the next five chars ASCII?" check which is
run after an "EI" sequence has been found. This check involves the
creation of a new object because peekBytes() calls subarray().

Unfortunately, the check is currently run on whitespace chars even when
an "EI" sequence has not yet been found, i.e. when it's not needed. For
the PDF in #2618, there are over 820,000 such checks.

This change reworks the relevant loop so that the check is only done
once an "EI" sequence has been seen. This reduces the number of checks
to 157,000, and speeds up rendering by somewhere between 2% and 7% (the
measurements are noisy).

61e6b576d4 Avoid an allocation in readCharCode(). 
readCharCode() returns two values, and currently allocates a length-2

passed-in object which can be reused.

in Mozilla bug 992125 by 4.2%.

7cbd057deb Avoid unnecessary array allocations in EvaluatorPreprocessor_read(). 
EvaluatorPreprocessor_read() is called in two cases. For the normal
layer, the args array it produces is used beyond the bounds of the loop
in which EvaluatorPreprocessor_read() is called.

But for the text layer, the args array is used in a very short-term
fashion. This change reworks things so that a single array is repeatedly
used for the text layer. This reduces total JS allocations for the
Spoorkaart map by 11%, and has similar effects on many other PDFs.

After PR 4982, the rendering of the first two pages of http://www.openmagazin.cz/pdf/2011/openMagazin-2011-04.pdf (from issue 215) no longer completes.

The issue is that we cannot have `args === null` in `PartialEvaluator_buildPath`, but *must* use an empty array instead.

In this patch I've also moved the `argsLength` variable definition in `EvaluatorPreprocessor_read`, to make sure that it's always defined.

51055e5836 Make IdentityCMaps more compact. 
IdentityCMap uses an array to represent a 16-bit unsigned identity
function. This is very space-inefficient, and some files cause multiple
IdentityCMaps to be instantiated (e.g. the one from #4580 has 74).

This patch make the representation implicit.

adf58ed687 Represent cid chars using integers, not strings. 
cid chars are 16-bit unsigned integers. Currently we convert them to
single-char strings when inserting them into the CMap, and then convert
them back to integers when extracting them from the CMap. This patch
changes CMap so that cid chars stay in integer format throughout, saving
both time and space.

When loading the PDF from issue #4580, this change reduces peak RSS from
~600 to ~370 MiB. It also improves overall speed on that PDF by ~26%,
going from 724 ms to 533 ms.

This change avoids the element stringification caused by for..in for the
vast majority of CMaps.

When loading the PDF from issue #4580, this change reduces peak RSS from ~650
to ~600 MiB, and improves overall speed by ~20%, from 902 ms to 713 ms.  Other
CMap-heavy documents will also see improvements.

f1d5ec407e Right-size |chars.length| and |type.length| in bidi(). 
This lets the JS engine resize the array elements buffer immediately,
thus avoiding some intermediate resizings. This can save multiple MiBs
of reallocation in text-heavy files.

c3c72948b9 Stop including cidmaps.js 
In b5b94a4af3, i.e. PR #4259, we stopped using cidmaps.js. Despite that, it's still included when PDF.js is built. At almost 0.5 MB (and approx. 7000 lines), this is currently the single largest file in the codebase.
Including such a large file in the builds, when it is not actually used, seems extremely wasteful; hence this patch.
