91b3765e97 Improve method naming in ItemRenderer
Use `visit_` for the pattern where the trait offers a default implementation that calls other
methods to do the actual work.

f04f0a3e48 GL backend: use direct layers for non-rectangular clips
Delegate the decision how to implement the Clip element entirely into the backend,
where the GL backend can now explicitly render
children into a layer, instead of the hack with a layer in the renderer's
state and the extra save/restore pair.

6a6a26569d Add support for rendering complex clip paths into cached layers
If the renderer supports it, clip elements with a complex clip render
the sub-tree into a cached layer.

75949e702c Prepare item rendering for children self-handling
The render function now takes a self_rc and returns a enum that permits
the implementation to handle rendering of children on its own and
thus make the caller skip that traversal step.

fd2d82e0a3 Flickable: adjust the thresholds
There must be a high enough threshold because the driver
of our screen is fuzzy and report changing numbers. We
don't want to be moving the Flickable too fast.

c94c223c3b Simplify item rendering loop
Instead of using the generic visitor, call `visit_children_item` directly on the Component.

This way we avoid the RefCell for the renderer and this will make it
easier to introduce items that decide to render the children themselves, with
their own property tracker.

33ae882506 Avoid shaping text twice per line when drawing paragraphs
Track the glyph range in the TextLine and use that to access the glyph buffer,
instead of calling shape_text() again.

247847cb54 Avoid unnecessary glyph buffer re-allocations
Store the result of all text shaping calls in one glyph buffer when laying out a

This paves the way of avoiding unnecessary shape_text calls when processing lines.

187294c00e Simplify glyph interface in TextShaper
* Impose no bounds on the associated Glyph type
* Report the byte offset only in shape_text - it doesn't belong into an aritrary glyph
* Move querying the advance into the TextShaper, where the MCU implementation can deal with missing glyphs
  without storing fallback values in the Glyph type

1a73460a6a Add basic text layout module for use with the MCU
This is based on the unicode line breaking algorithm (uses crate for
that), which also supports forced line breaks. The shaping is generic,
so on the MCU side we can do without at first.
