This is based on the unicode line breaking algorithm (uses crate for
that), which also supports forced line breaks. The shaping is generic,
so on the MCU side we can do without at first.
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.
Commit 738ac0dc01 increased the size of the ImageInner::StaticTextures variant,
which breaks the size assertions in the interpreter ffi build.
This changes fixes that by reducing the size of the ImageInner variant again by
moving all the fields into a separate struct.
The code was mixing logical and physical sizes, causing glyphs being
doubly scaled down. Instead, this patch introduces:
* Physical* and Logical* euclid length/size/rect aliases
* some extraction traits for getting the scalars in rects/sizes as lengths (until euclid has them
built-in)
* wrapper traits/types for safely extracting the physical font metrics the
compiler generates (i16)
* Fix a bug in the text height calculation where we failed to take the
descent into account
Enable with `SLINT_EMBED_GLYPHS=1` and select sizes like
`SLINT_FONT_SIZES=12,16`
This change just puts the data structures in place, rasterizes a fixed
subset, embeds that into the rust generated code and calls a backend
function for registering the font that is unimplemented.
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
* Use a jpg over an png, which is much smaller
* Do not round the image
* Change the image file extensions used in the demos to reflect the
actual image format being used
* Do not use symlinks for images: This breaks the WASM demos

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.
