292b96a0bf Make fnArray always be a plain array. 
This makes the code much simpler, and the extra memory use is tiny -- a vanilla
1000 element array is only 4000 bytes larger than a Uint32Array of the same
size.

6a75e45309 Allocate fewer objects when parsing 2 and 4 byte chunks. 
This is achieved by adding getBytes2() and getBytes4() to streams, and by
changing int16() and int32() to take multiple scalar args instead of an array
arg.

0866ad5bff Add a cache for glyphs. 
This reduces memory consumption for text heavy documents. I tested five
documents and saw hit rates ranging from 97.4% to 99.8% (most of the misses are
due to |width| varying even when |fontChar| matches). On two of those documents
I saw improvements of 40 and 50 MiB.

The patch also introduces the Glyph constructor, and renames the |unicodeChars|
local variable as |unicode| for consistency with the corresponding Glyph
property.

b3024db677 Estimate the size of decoded streams in advance. 
When decoding a stream, the decode buffer is often grown multiple times, its
byte size increasing like so: 512, 1024, 2048, etc. This patch estimates the
minimum size in advance (using the length of the encoded stream), often
allowing the smaller sizes to be skipped. It also renames numerous |length|
variables as |maybeLength| to make it clear that they can be |null|.

I measured this change on eight documents. This change reduces the cumulative
size of decode buffer allocations by 0--32%, with 10--20% being typical. This
reduces peak RSS by 10 or 20 MiB for several of them.

d0253c8291 Don't get bytes eagerly when creating {Jpeg,Jpx,Jbig2}Stream objects. 
This avoids lots of unnecessary work when such streams are referred to via
fetch(), and so their bytes aren't subsequently read. This is a large
performance win on some files.

f12d588258 Add an ensureRange() call to ChunkedStream_makeSubStream(). 
By checking if the data is all present before making a substream, we avoid
cases where we parse part of a stream and then throw a MissingDataException
part-way through, which forces us to later re-read the stream -- possibly
multiple times. This is a sizeable performance win for some cases when file
loading is slow (e.g. over the web).

076b3433b4 Improved annotations' display/behavior. 
Added an "InteractiveAnnotation" class to homogenize the annotations' structure (highlighting) and user interactions (for now, used for text and link annotations).

Text annotations:
The appearance (AP) has priority over the icon (Name).
The popup extends horizontally (up to a limit) as well as vertically.
Reduced the title's font size.
The annotation's color (C) is used to color the popup's background.
On top of the mouseover show/hide behavior, a click on the icon will lock the annotation open (for mobile purposes). It can be closed with another click on either the icon or the popup.

An annotation printing is conditioned by its "print" bit
Unsupported annotations are not displayed at all.

4a66eccedc Rewrite Lexer_getNumber. 
Now, it computes the numbers with only basic arithmetic operations, without first creating a string and then calling parseFloat.
The new function doesn't behave exactly the same as the old one.
In particular, the old behaviour was that when there was a number immediatly followed by an 'E', the 'E' was consumed. Now it's not. It allows for "glued" numbers and operators.
Also, the new function is faster and consumes less memory.

<< /S /URI /URI (http://127.0.0.1/v/index.php/File:Logo.png >>

The URL should be wrapped in parentheses, but sometimes it isn't.
Consequently, the value is interpreted as a Name (because of the leading "/"),
and the resulting object is `{name: "v/index.php/File:Logo.png" }`. Obviously,
this is not a string, so `url.indexOf` throws an error here.

Rob Wu
43847d7ff8 Set eof to true at the end of a FlateStream 
At the initialization of `Lexer_getObj` (in `parser.js`), there's a loop
that skips whitespace and breaks out whenever EOF is encountered.
(https://github.com/mozilla/pdf.js/blob/88ec2bd1a/src/core/parser.js#L586-L599)

Whenever the current character is not a whitespace character,
`ch = this.nextChar();` is used to find the next character
(using `return this.currentChar = this.stream.getByte())`).

The aforementioned `getByte` method retrieves the next byte using
(https://github.com/mozilla/pdf.js/blob/88ec2bd1a/src/core/stream.js#L122-L128)

      var pos = this.pos;
      while (this.bufferLength <= pos) {
        if (this.eof)
          return -1;
        this.readBlock();
      }
      return this.buffer[this.pos++];

This piece of code relies on this.eof to detect whether the last character
has been read. When the stream is a `FlateStream`, and the end of the stream
has been reached, then **`this.eof` is not set to `true`**, because this check
is done inside a loop that does not occur when the read block size is zero:
(https://github.com/mozilla/pdf.js/blob/88ec2bd1ac/src/core/stream.js#L511-L517)

      for (var n = bufferLength; n < end; ++n) {
        if (typeof (b = bytes[bytesPos++]) == 'undefined') {
          this.eof = true;
          break;
        }
        buffer[n] = b;
      }

This commit fixes the issue by setting this.eof to true whenever the loop is not
going to run (i.e. when bufferLength === end, i.e. blockLen === 0).
