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.

According to the specification, http://partners.adobe.com/public/developer/en/ps/sdk/5116.DCT_Filter.pdf#G3.851943, the content of the marker segment should begin with `Adobe`, and not `Adobe\x00` as the code currently look for.

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`.

c2c54257f2 Prevent setting |isStandardFont| to |undefined| for non-embedded fonts 
This is a very small follow-up to PR 5536, which sets `isStandardFont` to `false` instead of `undefined` (as currently happens for some font names).

Since the patch is so small, I hope it's OK to also fix an unrelated copy-and-paste error in a comment that was added in PR 5260.

1fea44ce14 Ensure that |get fingerprint| doesn't fail if the ID is not an array (issue 5599) 
According to the [PDF specification](http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/PDF32000_2008.pdf#page=51) the `ID` should be an array. To prevent errors if the PDF file violates that part of the spec, check that the `ID` is actually an array.

Fixes 5599.

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.
