For the MCU port, we need to proccess the image to save them in the binary
in a convenient format.
This patch start this work by trying to anaylyze what format should an image
be using, and saving it as a texture in the binary.
The current graphical backend and the C++ frontend are not yet supported
This will allow later to be able to operate on the binding despite the
element is borrowed.
Since the Binding itself is in a RefCell, the analysis don't need to
be anymore.
To do this change, a small change in the binding_analysis logic was required
which means that we will now detect binding loop if a binding was causing
two binding loop. (before, only one binding loop was detected)
Pass the sub-component as a parameter in enter_component(), as it's needed in the C++
implementation, it's readily available (no need to unwrap again) and Rust will need it, too.
Avoid creating an intermediate array of items to free the graphics resources.
Instead call run-time function with the item tree as a parameter, which is traversed.
It's practically the same data structure that was previously created, except
that it is shared/global and has little holes for the dynamic tree items, but those are easy to skip.
In ComponentDescription only keep a exported_globals_by_name that
maintains the index in the compiled_globals vector and in there store
the public properties of global singletons.
When exporting an global multiple times under different names, make sure
that they alias in the generated code.
As a consequence, the compiler maintains the original unique name and in
Rust and C++ makes only the exported names public. In the interpreter
the internal name is theoretically still accessible from the outside.
Don't put them in a fake expression.
This simplifies a bit the expression handling, and will make
possible to fix analysis that needs a vew into the aliases
If we were to add `sixtyfps:🪟:Window` to the re_exports, then
this clashes. We might rename the former, but this is a cleaner naming
in any case.
Relates to #333
And do some passes before inlining
We will need the list of components before inlining in order to generate
them if we disable inlining
So we can do some passes on each component before they are inlining
I tried to put the flickable pass in that list, but it did not work
if the Flickable itself is the root of a component
