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.

some array copying.

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

dd2adf6200 Fixes mesh fill pattern with optional matrix (#5020) 
In the referenced issue, there is a PDF which uses a fill pattern which does not
have a matrix defined. This causes singularValueDecompose2dScale to fail with
undefined property error when accessing elements of that matrix.

This fix will only use the matrix when it is defined. The output for the PDF in
question now looks identical to chrome and preview with respect to the gradient
fill pattern.

a483c80fc3 Make QueueOptimizer easier to read. 
QueueOptimizer is really hard to read. Enough so that it's blocking my
efforts to streamline the representation used for operator lists.

This patch improves its readability in the following ways.

- More descriptive variable names make the sequence checking much clearer,
  as do additional comments.

- The addState() functions now return the index of the first op past the
  sequence, instead of setting context.currentOperation to the last op of
  the sequence.

- The loop in optimize() is clearer.

- The array modification in the fourth addState() function is much clearer
  -- we're just removing trios of ops.

- All four |addState| functions are now more consistent with each other.

I used some debug printfs to find documents where these optimizations are
used and then checked that the number of optimized ops was the same before
and after my changes.

db866945b7 Improve how DecodeStream handles empty buffers. 
DecodeStream currently initializes its |buffer| field to |null|, which
is reasonable, because lots of DecodeStreams never need to instantiate a
buffer. But this requires various special cases in the code.

This patch change it so DecodeStreamClosure has a single empty
Uint8Array which gets shared between all buffers upon initialization.
This avoids the special cases.

DecodeStream.prototype.ensureBuffer() is really hot, and this removes a
test from the fast path. For one 226 page scanned document this sped up
rendering by about 2%.

17170af3c7 Avoid allocating return object in EvaluatorPreprocessor_read(). 
This function can be called 100s of 1000s or even millions of times, and the
allocated return object accounts for 10% of all GC thing allocations for some
documents. It's easy to avoid, which reduces stress on the garbage collector,
and this patch does that.

22a0e7fe65 Optimization for FlateStream_getCode, making more pdfs parsable. 
This commit cleans up the FlateStream_getCode method, and removes a few error
conditions.
Previously it would fail if the codeSize is less than maxLen if end of stream
is reached. However in the document linked below there is a sub-stream
(the one starting at pos 337) which has maxLen set to 11, but actually
contains only 10. After breaking the sanity check still applies, and in this
case passes validating codeSize(10)==codeLen(10).

0a42edf82f Optimize JPG.js receiveAndExtend for 1 bit case. 
Profiling showed that receiveAndExtend is frequently called with the length of
one bit. This happens for example in decodeBaseline.
For a single bit, the loop and shift in receive, as well as the shifts in
receiveAndExtend are overhead.
This shortcut manually calculates the shifts by either returning 1 or -1 from
receiveAndExtend by reading the bit and deciding on the return value.
While it comes with an overhead for each non-one length, the speedup is at about
10% in the hot parse/decode path.

This change makes the 4 conversion loops look the same.
It optimizes access of the array length and access of the property
numComponents, which is known to be constant.
