Move "internal" crates into the `internal` directory. This first batch
includes most of sixtyfps_runtime but leaves the rendering backends
alone for now.
pre-commit applied some cleanups to the moved files:
- Consistent newline at end of file policy
- trimming trailing whitespace
- Formatting Cargo.toml files.
This patch takes care of the lowering of events/coordinates arrays as
path data, which originates from a `commands: ...` string of SVG path
commands.
In order to minimize the path specific code in the generator, the
compile_paths now generates a Vec<Expression> for the events and
coordinates.
A `Path` with `MoveTo`/`LineTo`/etc. sub-elements now maps to an Expression::PathData of type
Type::PathData.
The llr lowering creates an Array of Type::PathElement, which is casted to PathData.
This only covers the element case. The compiled path events are still todo.
The main thing here is that the Component are in different data structure
depending on whether they are sub-component global component or repeated component
Then the properties at are the right place and there will be no more lookup
in the base. The PropertyReference knows how to access which property via which
element and such.
The idea is that it will be easier to lower from this representation than
what we currently do in each language backend.
This commit is still WIP, it is far from finished
