Remove leftovers like #Type, reduce indentations
to avoid markdown block quotes, etc.

This reverts merge request !309

Extend the PangoUnderline and PangoOverline enumerations to
cover dashed and dotted variants of the various lines, add
api to PangoRenderer to render such lines, and implement it
in the cairo renderer.

Convert link syntax, and summaries.

Replace gtk-doc'isms and use gi-docgen links instead.

Cross-gir links are still an open issue.

We want to use pure markdown, since docbook
is going away as the intermediate format.

Avoiding this warning:

../pango/pangocairo-render.c:506:19: warning: assigning to 'char *' from 'const char *' discards qualifiers [-Wincompatible-pointer-types-discards-qualifiers]
  for (row = 0, p = name; row < rows; row++)
                  ^ ~~~~

Implement overlines in PangoRenderer.
This adds a new render part, and mirrors
the machinery we have for underlines and
strikethrough.

Instead of a [SPC] hex box, just render a
centered dot, as is commonly used to indicate
space. Also render synthetic glyphs for tabs
and newlines.

This makes single-paragraph mode prettier.

For ignorable characters such as U+00AD, Soft Hyphen,
render a hex box with their 'nickname', which is a
2-6 character short form such as SHY.

Even if a font has no space glyph, we don't want
to render a hex box for it, since just rendering
nothing does a decent approximation of space.

Abolish the PANGO_ENABLE_BACKEND and PANGO_ENABLE_ENGINE
defines. All backend-only apis are moved into private
headers, all apis that were engine-only are marked as
deprecated, since engines are.

The example code is not correctly escaped, and gtk-doc has become
slightly more strict. This is a good chance to port this bit of the API
reference to Markdown, and avoid all issues in a future without inlined
XML.

s/bytess/bytes/ in a warning.

Improve the behavior of the cairo renderer to take
alpha into account even if no color specified.

https://bugzilla.gnome.org/show_bug.cgi?id=773767

Make PangoCairoRenderer use cairo_set_source_rgba() to apply
colors with alpha. Note that this means we are only using the
alpha if the corresponding color has been set.

Round lsb.

        Make layout and layout-line default renderers go through
        draw_glyph_item(), which then by default falls back to
        draw_glyphs().  The advantage in draw_glyph_item() is that it
        has access to the text and cluster information.
