2e5ab9c9eb Remove unused helper functions in src/core/core_utils.js

c92d4be973 Remove readUint32 usage from the isTrueTypeFile function 
This is the only `readUint32` usage in the `src/core/fonts.js` file, and it can be trivially replaced with a string comparison.

f924526f1a Remove the int32 helper, and replace it with DataView usage, in src/core/fonts.js 
This helper function only had a single call-site, and it's easily replaced with a `DataView` method.
Additionally, to hopefully make future re-factoring easier, create a `DataView` for each TrueType table.

a69b9ad033 Ensure that the built "hmtx" font table has valid widths (PR 21072 follow-up) 
With the changes in PR 21072 the `string16` helper is no longer being used when building the "hmtx" table, which accidentally removed the development mode assert.

8f56ee2ae9 Use a TypedArray when building the "hmtx" font table 
In this case it's trivial to compute the size of the data upfront, hence we can use a TypedArray which should be more efficient than a string.

2d8b25cd6d Update the position when calling ChunkedStream.prototype.getBytes without a length 
Currently the code only updates the position when the length is defined, and it seems that this has "always" been wrong. Originally I believe that the `ChunkedStream` class was essentially a copy of the `Stream` class, and that implementation had the same problem until PR 20593.

Hopefully there's no code that relies on the current incorrect behaviour[1], since testing every aspect of the `ChunkedStream` implementation can be tricky given that these things are timing dependant.

---

[1] If there are, fixing those call-sites may be as easy calling `ChunkedStream.prototype.reset`.

654985c621 Add constants for defining the initial BBox and Float32 BBox 
Nowadays there's a lot of places in the code-base where we need to initialize or reset bounding boxes. Rather than spelling this out repeatedly, this patch adds new `Array`/`Float32Array` constants that can be copied or used as-is where appropriate.

Avoid as much as possible to have intermediate canvases 
We try to detect in the worker if some patterns or groups need to be drawn or not in isolation.
When they don't, we just draw them on the main canvas instead of drawing on a new canvas.
A pattern or a group is considered as being in isolation if it has some compositing rules or some transparency.

It improves the rendering performance of the pdf in bug 1731514.

7b1b1a9153 Reduce allocations in CFFCompiler.prototype.compileIndex (PR 21053 follow-up) 
It's possible to compute the final index-data size upfront, thus avoiding a bunch of intermediate allocations during index compilation.
This also means that a TypedArray can be used, rather than a plain Array, making it more efficient to insert the `objects` data.

This helps PDFs with large and complex CFF fonts the most, for example the PDFs in https://bugs.ghostscript.com/show_bug.cgi?id=706451 render ~40 percent faster (based on quick measurements in the viewer with `#pdfBug=Stats`).
