61ff7f0e1c Handle full "display" property 
In CSS Display Module Level 3, the "display" property gets a long
representation allowing:

- a clear separation between inner and outer display type,
- new supported types (contents, run-in, flow-root…),
- inline list items.

This commit allows the (retrocompatible) new long syntax for "display". It also
supports the "flow-root" value. It doesn’t support values related to ruby, and
it doesn’t support the new "contents" and "run-in" display types.

This work gives the possibility to simplify the code in the block_*_layout
functions, and to improve the overall layout.

Related to #36.

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…

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.

231736d73e Use the original SVG tree when drawing patterns 
In Pattern, we want self.tree to be the pattern tree when we call draw(), but
we want self.tree to be the original SVG tree for everything else, like finding
defs.

This commit replaces self.tree with the original SVG tree after we call draw().
