3aca9f1f84 Change the resume_at and skip_stack structure 
Many operations, including page breaks, require a pointer to a specific
position of the box tree. For example, we used to have this structure to point
to the beginning of the first child of the second child:

(1, (2, None))

We now use:

{1: {2: None}}

This change is the first step to handle parallel flows (see #36). It doesn’t
change anything to the layout for now, but it allows us to store multiple
pointers in the same structure.

The next step is to handle multiple pointers in skip_stack during boxes layout.
It means that most of the *_layout() function need an extra for-loop to manage
multiple skip stacks.

We’ll then need to split new types of boxes: table cells, floats, absolutes…

that already takes care of (0, 0) values.

2e96bdee35 Simplify API to get intrinsic size of images 
The previous API wasn’t stateless, as it sometimes required to call
get_intrinsic_size before accessing intrinsic_ratio. The new API offers a
single method to get width, height and ratio.

694eddbc71 Embed images once 
Images were already embedded once when included in the same stream.
Unfortunately, patterns have their own streams, meaning that a pattern used
multiple times includes the image each time. That’s especially bad for
different boxes using the same background, as backgrounds are drawn as
patterns.

Fix #1414.

e30907c869 Simplify when begin/end text tags are inserted 
The previous behaviour was introduced by 603ee26 as an optimization.
Unfortunately, it was not correct because text decoration can’t be drawn inside
the begin/end text tags. Generated PDF files were incorrect, leading to buggy
rendering by Ghostscript.

51b90ecf26 Don’t crash with Pango 1.42 
Debian stable (Buster, 10) includes Pango 1.42. Until the next version of
Debian (Bullseye, 11) is released, keep a workaround to avoid crashes.

This workaround is not documented on purpose, support of Pango 1.42 will not be
improved. Also note that WeasyPrint with Pango 1.42 will suffer from #1199.

04985cb5ab Use image id instead of increasing index for image keys 
Pillow images are stored in a cache, to be sure that we use the same image when
we have the same URL (and don’t try to retrieve it twice).

Using the image id as a key prevents WeasyPrint to store the image twice in the
PDF, with a large gain of time and size.

eb245c6e82 Replace directionality characters with zero-width space 
As these characters were removed to avoid crashes when breaking lines, indices
returned were wrong and could cause crashes.

Replacing them with zero-width spaces adds a hack to the hack, but it keeps the
same indicies and should be harmless for rendering.

Of course, the real fix is to have real bidi support.

Fix #1336.
