8bb96db3a0 Use CSS.supports instead of '..' in ....style 
document.documentElement.style is null in some XML documents.
The previous snippet caused the following error:

Uncaught TypeError: Cannot use 'in' operator to search for 'animation' in null

To fix this bug, `'animation' in document.documentElement.style` has been
replaced with `CSS.supports('animation', '9s')`. This method was introduced
in Chromium 28, but it is not necessary to detect whether this method is
supported because the required createShadowRoot method for embeds is not
available in Chromium 32 and earlier.

00746011a3 Managed preferences for Chrome administrators 
Implement support for managed preferences. This feature allows users
(administrators) to easily change the default settings of the PDF Viewer for
all Chrome or Chromium browsers within their organization.

- http://www.chromium.org/administrators/linux-quick-start
- http://www.chromium.org/administrators/policy-templates

Administrators can read one of the previous links to learn more about creating
policies. We want to auto-generate these templates, but there are no public
tools for doing that. It will be added in the future, see:
https://code.google.com/p/chromium/issues/detail?id=389061

28687bca75 Optimize CMap.prototype.forEach(). 
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.

87dacba9a6 Feature detection after downgrading the browser. 
If a user downgrades from Chromium 35+ to 34, then the PDF Viewer
extension will not work any more because the extension assumes
that certain features were available based on the cached feature
detection results.

To resolve this problem, all feature detection scripts run again
if the browser was downgraded.

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.

bb13fb939e Initialize PDFView.url = '' 
The absence of this property caused the following error in PDFView.download:

   Cannot read property 'split' of undefined

This property was unset when the PDF was loaded through a typed array instead
of a URL. With the fix, the file name will default to "document.pdf", as
defined by getPDFFileNameFromURL in web/ui_utils.js

856e1c600b Optimize Ref_toString(). 
I have a large PDF where this function is called 1.6 million times
during loading. Minimizing the string concatenations reduces the
cumulative allocations done by Firefox within this function from 113 MB
to 48 MB.

c7f02d2c8e Minimize memory usage of font-related arrays. 
This patch replaces some vanilla arrays with typed arrays, and avoids
some array copying.

It reduces the peak RSS when viewing

from ~940 MiB to ~750 MiB, and reduces its load time from 83 to 76 ms.
