This reverts commit 2dcbc45cd6.
It breaks loading of the printer demo in the editor because in
import_file we fail to return the absolute path and thus end up
importing common.60 too many times.
`ComponentHandle` offers a richer API of common functions, such as
`show()`/`hide()` as well as the new `clone_strong()` - that should help
to prevent mistakely created strong reference that may cause leaks.
Fixes#188
Re-add the compiler configuration internal API. When `from_string` is complete then we can switch to the new public
compiler config API.
And use diagnostics accessor functions.
The problem is that the backend is using the `meta_property_listener` to know
if the layout must be updated, but the C++ code would not register a dependency
NOTE about the test: The test doesn't really test that it works because
the test backend don't have a meta_property_listener and apply the layout
inconditionally in sixtyfps_send_mouse_click
Remove the `application` infix from `register_application_font`, to
reduce the changes that it might be interpreted to be a function that
also changes the default font in all text elements.
This is just a starting point, to be turned into a real Transform
element later, along with syntactic sugar to turn rotation, etc. into a
transform matrix in the generated output.
In the nightly it appears that `no_mangle` is now considered "unsafe",
so we need to allow that in the ffi modules. For the layout code this
patch also creates that ffi module with prefixed function names, like in
the other modules and only allows unsafe in there.
Allow converting a brush to a color. In the case of a gradient, the color of the first stop is returned.
For the C++ generator this requires adding the extra case of explicitly
calling the `Brush(const Color &)` constructor, despite it being implicit,
in order to generate the correct code when we have IR that casts twice:
```
Expression::Cast {
from: Expression::Cast {
from: Expression::Cast {
from: Expression::NumberLiteral(...),
to: Type::Color,
}
to: Type::Brush,
},
to: Type::Color,
}
```
