d2186593c0 Pass the ItemRc to each draw_function

80830bbece MCU: Refactor the renderer in a LineRenderer 
The LineRenderer is going to be a public type which can be used
by the MCU board support to draw.
Right now, it is used by the old code

38abeaec41 text handling: clean up font traits 
Separate the text shaping functionality from font metrics by having a
FontMetrics trait next to the TextShaper. AbstractFont is the combining
super trait. This allows eliminating the font height member from
TextParagraphLayout and improving the overall naming of fields and
types.

Finally, this prepares the API for composability of TextShaper for font
fallback handling.

93b5eda82e text handling: simplify glyph data structure handling 
Replace the abstract glyph trait with a glyph struct. That way the text
layout code can operate properly on a struct with fields, instead of on
functions on a trait (some of which returning a mutable reference). The
input is a glyph with offset, advance, etc. - everything needed for the
layout and the output is a position along with the platform specific
glyph data.

b6e7db0221 Minor cleanup in the MCU text handling 
Replace the use of Option for the associated glyph type with a
struct that can later implement a trait.

cc1aad8ce9 MCU: fix panic in the renderer 
Sometimes, BorderRectangle clips can get negative if the intersection
of two rectangle leads to a rectangle that is smaller than the previous
rectangle, but because of floating point error while computing the max
position, the resulting clip may still be negative.
Add a small value to compensate that error

afb59cba29 mcu: fix popups not visibly closing 
When closing a popup, notify the platform window, so that the mcu
backend can remember that region and start the dirty region with it.

Also, free all the rendering cache items of deleted items, to avoid accidental re-use
when re-opening a popup.

ed3419ac0e MCU renderer: Fix another rounding error 
We need to use round_in() instead of cast() as cast() discard

b510c2f7a2 MCU: fix drawing clipped images

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.
