Initial support for truetype fonts in the software renderer
...
This works, but it's super slow as for every glyph the font is loaded
again and the glyphs are rasterized every time they're drawn.

Remove internal duplicated FontMetrics trait
...
There's also one in the textlayout module and this was is just confusing as a trait.

Simplify glyph handling in the software renderer
...
Remove platform glyph abstraction, just use non-zero u16 as glyph index
like everyone else. As a bonus, this reduces the memory consumption of
the glyph buffers per glyph from a size of a pointer to the size of the
u16.

Always set Window.default-font-size
...
Permit the style metrics to provide a `default-font-size` and bind that
to the `Window` if set. If not provided, then the backend can set a
`default-font-size`. By ensuring that the value is non-zero at run-time,
we can later introduce a rem unit that can act as factor relative to
this non-zero font size.

Simplify FontRequest
...
It doesn't have to be generic as mostly the frontend code creates it with logical lengths.

Change FontRequest to be a generic over the length
...
The API uses a logical length for pixel sizes and letter spacing,
but the renderer will need the physical length eventually.

Move physical length definitions into the software renderer
...
Their choice of i16 is specific to the software renderer. In say the Skia renderer
the physical coordinate space would still use Skia's Scalar (floating points).
