The metrics properties and the implementation of layout_info needs to
strictly reading cross-axis properties to avoid circular dependencies.
This patch applies a INT_MAX / 2 on the cross-axis to QStyle when
querying. Mostly the styles appear to just add/subtract margins, so this
value should not produce overflows while still providing an
approximation of "infinite" :)

The srgb workaround from commit a0e827e200
appears to work with the AMD GL driver, without which the GL context
creation works (as tested by the reporter).
So instead of panicing, fall back to the glutin default with possibly an
srgb framebuffer, when trying to create a GL context. If that also
fails, provide a better error message than "called unwrap on an err".
cc #481
Even if SIXTYFPS_BACKEND_GL is set to OFF, we would default to enabling
X11, which translates to enabling the x11 feature, which in turn
implicitly activates the GL backend. In addition, the interpreter Rust
API crate also enables the GL backend in its defeaults.
In order to make it possible to turn off the GL backend, three changes are necessary:
* The default backend no more selects a default :-). Instead the Rust
API crate, Rust interpreter API crate and the CMake project define
the same features and defaults.
* The C++ crate depends on the interpreter without its defaults (which enable GL)
* In CMake the X11 and Wayland features become dependent options, that
are only show in the CMake configure UI if the GL backend is enabled.
This way a GL-disabled build won't also pass --features x11.
This can be reproduced by deleting the last item of the printer queue in the
printer demo.
It is a regression showing up because we now emit the MouseExit event after
the mouse grab as released.
The problem is that we upgrade the weak item, and call geometry() on it.
Calling geometry will re-evaluate the layout cache which will re-evaluate
the model which will result in the component being removed and the cache
entry having less item than expected.
It is ok to simply return 0. for these layout location since the item will
disapear anyway.
As tests/cases/examples/image_rendering.60 itself demonstrates, the png file
should be loaded into the CPU side image cache once, but the two textures
should be cached independently.
cc #465
Normaly, fields od structure exposed to .60 need to be in lexicographic order
for themto work in C++ with agregate initialization, but since that field is not
in the .60 Struct, it needs to be last so it is default initilalized
Improve the granularity of the borrow of the mapped window, to avoid
that when applying window properties we recurse into a borrow due to
the call for setting the geometry triggering a notify that borrows.
Like CSS image-rendering it has "smooth" and "pixelated" options.
Only OpenGL has been tested right now, have not tested WASM or Qt.
Right now the first instance of a @image-url() will set the scaling
for that specific image. The same image used from memory on the otherhand
can all have a different scaling property.
Similar to the other window item properties and also similar to how the
Qt backend handles this, fetch the background color in
apply_window_properties().
If the root item is a Window, then we use the default-font-* properties as the basis
for all unspecified font properties in text rendering.
This patch centralizes the code for retrieving that in the runtime window.
If this becomes a performance bottleneck, then we could cache it in a
box-pinned property in the run-time window.
When the window is mapped, the scale factor is brought up-to-date. Only
after that we can receive a resize event or a window scale factor
changed event.

Remove the internal name again and pick the first exported one when
assigning ids. This avoids internal names showing up in code completion
or the internal types leaking into generated code.
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.
