This adds an ImageBuffer and PixelBuffer type for SharedVector
backed images. The documentation explains how to use this
with low-level rendering functions and the popular image crate.
Fixes#387
Further build on b3529d1b75 and move the
strong/weak reference dance into the API crate out of the generated
code.
Saves ~21k llvm lines on the printer demo (debug).
It's also possible to move the as_pin_ref() bit, but that didn't
really give any savings overall.
The binding setup functions (set_binding, set_animated_binding, etc.)
are taking the binding basically as an `impl Fn() -> T`, which means
each call site creates a new copy. The bodies of these can be quite big.
Since most of our uses follow the pattern of just capturing the
samereduce the number of copies needed parameter, we can reduce the
number of copies needed by providing wrappers.
With rustc 1.54.0 on my mbp and debug, the build time of
touch ../ui/printerdemo.60
cargo rustc
goes from 1m:15s down to 42s, and total llvm lines goes from
2079842 down to 1134237.
This requires some gymnastics to get right as the information
need to be passed to the compiler despite having no direct dependency
between the compiler and the runtime or backends.
So use a file in the build directory to tell the default style
cc: #83
and replace it with the internal, re-exported WindowHandleAccess
one.
Strictly speaking, this is a breaking change. In practice the
returned type of this trait was in `sixtyfps::re_exports`, so any
public use is questionable :)
That's all it is nowadays, it's a wrapper around Rc<Window>. It's not an
alias because we need to also "wrap" it to C++ via cbindgen, but that's
about it.
Using Olivier's idea to check the meta tag, we can distinguish rustdoc
from "the rest". The html is included in mdbook by directly by
symlinking head.hbs.
The preview is now in sixtyfps-docs-preview.html and the highlighting in
sixtyfps-docs-highlight.html. This faciliates reusing the preview from
C++ while using a different HTML file later for syntax highlighting.

Needed for #281
Load our highlight.js snippet that we also use for the mdbook tutorial.
Once change we need to apply on top is that the rustdoc CSS theme does
not currently provide hljs classes that change with the currently
selected theme, so instead we're mapping the classes to the CSS classes
that are used for Rust syntax highlighting. Those change with the
current theme.
