23d3964a0d Add boilerplate for text items 
Forward the text and color properties to the rendering backend, where
right now we just rendering all the glyphs into a dedicated texture.

Next steps are a glyph atlas texture, blending the specified color with
the alpha of the glyphs, configurable size and family, shaping with
Harfbuzz and may more things.

a7d5bd9f59 Minor rendering cleanup 
Remove the x/y parameters from the rectangle primitive. They're always zero
since we always render with a transformation
matrix.

6110e4952d Move item rendering related code into a separate module 
.. and keep less code in the central lib.rs.

3142883ca8 Render the contents of image elements 
The source property is a path relative to the path of the executable.
That is still rather inconvenient. It would be more convenient to make
it relative to the source file, but the corresponding proc-macro span
source_file() accessor is not public/stable.

Perhaps there's a way of doing this also through the generated code and
std::file!().

e144e885e1 Generalize the offset state in the rendering loop 
Using a transform allows for additional properties such as scale and rotation
later.

6ba90975b8 Further cleanup of the internal run_event_loop 
Let the callback take a frame and that's it. Then the caller can take
care of presenting it, etc.

c26a2a1562 Fix GL context state handling 
Make our GL context not current when done with the initialization
and make it current for the duration fo primitive creation and frame
rendering.

0b807190c7 GL Renderer cleanup 
Get rid of the vertex array object that's not really used. We do bind the binding
manually right now anyway and this can be reintroduced later.

5986d5f2b8 More visitor cleanups 
Provide a non-mutable visitor as well, as the actual rendering loop doesn't need
to change the items fortunately.

f22b18584e Remove the cells in CachedRenderingData 
Since we have a mutable accessor to this structure, we can skip the cells and make the code easier to read.

743ad34099 Renaming RenderNode to CachedRenderingData 
The name node suggests some kind of connected (tree) data structure, which
isn't quite what it is. It really is meant just
to be a way of storing cached rendering data for this item.

Replace the use of kurbo's primitives with lyon/euclid. This means less data copying,
conversion and also no annoying precision
casts.
