richtext: allow any value type in metadata
Users may want to associate complex metadata with spans, such as objects
that interactive spans refer to. Let users store them directly instead
of having to roundtrip through strings.
Performance wise, this makes storing string values more expensive,
because they have to be put in interface values. On the other hand,
users can now store pointer-typed values for "free". Additionally, if
users are concerned about performance, then they likely aren't
dynamically allocating strings and can use pointers to strings instead.

markdown: bump default size
12 isn't readable on some low-dpi screens, at least not well.
Use a more reliably readable default size and allow applications
to override as needed.

outlay: return actual size from Grid.Layout
Don't make the Grid as large as the Max constraint. Instead, make it at
least as large as the Min constraint, but otherwise limit it to the
height of the rows we actually drew.

outlay: don't truncate grid when using locked rows
The old code accounted for the number of locked rows twice, which caused
it to render fewer total rows than needed.

markdown: fix nested emphases
This commit fixes a markdown rendering bug that would clear
the bold/italic state of text when either style ended, preventing
proper nesting.

richtext: fix line wrapping on style boundaries
The change to Gio's text shaper that dropped support for breaking
within words subtly broke an assumption used by richtext's line wrapping.
This manifested as segments of text choosing not to wrap at style
boundaries.

markdown: [API] revise text styling api
This commit enables consuming code to configure the text sizes
and colors generated by the markdown renderer by setting optional
fields on Renderer.Config. Additionally, the default header sizes
are now sane and no longer map 1:1 to the material design header
sizes. This commit has the side effect of dropping the dependency
on the material package.

outlay: implement grid layout
This patch implements a two dimensional grid that functions much
like layout.List. The API accepts a closure to provide the dimensions
of each row and column, and a separate closure to supply the contents
of each cell.
As an implementation simplification, all rows are presumed to have
the same height as the row with index 0, though we hope to remove this
constraint in the future.
Additionally, the grid supports locking the first N rows to the top
of the grid, though it does not currently support a corresponding
feature for columns.
