This includes the cache of decoded images, the HTMLImage element support
and the SVG rendering adapter.
The objective is that Image holds an ImageInner, which is not a path
anymore that the backend has to process, but instead always either
decoded image data, a pointer to a static texture or an SVG tree that
can be rendered to the desired size.
This avoid repeating the enums both in the compiler and in
the runtime library, and register them in a bunch of other places.
So it should be easier to add enums and enum values
Since cbindgen doesn't see through the macro, generate the enum
manually
With ImageInner::StaticTextures (the variant) and StaticTextures (the
struct), we need to disambiguate for the generated enum contructor
functions. This is done by prefixing the enum variant with their name.
With the help of dark-light crate this is now exposed as dark-style
boolean property in NativeStyleMetrics.

- We need to make sure that the initialization of global is in the right order.
- In C++ and rust, we need to add accessor to the global component
- There can be `PropertyReference::Global` in binding of globals
- The interpreter globals need to hold references to the global they may depend on
Fixes#175
Fixes#909
Since we declare the struct in C++, we don't need to declare it in
rust for cbindgen anymore, as long as we expose the Size2D type from
euclid to the cbindgen_private namespace
Add the graphics state enum to the callback, too. When we add support for different backends,
it would be nice if it didn't require an API change.
It's duplicated from Rust
because it doesn't provide values. The WebLG one doesn't make sense for C++ and
the proc address closure isn't ffi safe.
(It could be manually bridged thought)
This API allows specifying a callback that will be invoked when setting
up graphics (great for compiling shaders), before rendering a frame (but
after the clearning of the surface background), after rendering a frame
(before swapbuffers) and when releasing graphics resources.
