33ae882506 Avoid shaping text twice per line when drawing paragraphs 
Track the glyph range in the TextLine and use that to access the glyph buffer,
instead of calling shape_text() again.

247847cb54 Avoid unnecessary glyph buffer re-allocations 
Store the result of all text shaping calls in one glyph buffer when laying out a
a paragraph of text.

This paves the way of avoiding unnecessary shape_text calls when processing lines.

187294c00e Simplify glyph interface in TextShaper 
* Impose no bounds on the associated Glyph type
* Report the byte offset only in shape_text - it doesn't belong into an aritrary glyph
* Move querying the advance into the TextShaper, where the MCU implementation can deal with missing glyphs
  without storing fallback values in the Glyph type

8d4c645346 Change the paragraph text layout callback to take glyphs

implementation of features like elision or letter spacing in  a shared code.

a947ec1441 Simplify glyph interface 
The textlayout module does not need to impose the exact glyph struct layout.

This paves the way for glyph based rendering.

42a0f605ad Add an paragraph layout helper function to the corelib textlayout 
The objective is to use this in the MCU backend and replace layout_text_lines() in the GL backend in the future.

1a73460a6a Add basic text layout module for use with the MCU 
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.

583c7a1b80 Fix C++ build 
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.

f1dae75d53 Fix interpreter ffi build 
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.

f912ec7e6b Fix scaling of glyphs and improve type safety in the MCU backend 
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

304e06f758 Begin rasterizing glyphs for glyph embedding 
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.
