5c8163d7a7 Introduce a new rendering primitive enum in the graphics module 
This shall become the successor to RenderingInfo. For now it's just a
place holder, but the idea is that backend creates the opaque primitive
that holds this public rendering primitive, exposed via the
HasRenderingPrimitive trait.

e7fd69bad1 Rename internal types 
Rename the backend specific RenderingPrimitive to LowLevelRenderingPrimitive,
in order to make room for a high-level RenderingPrimitive enum that's public.

f2662f0884 Simplify image primitives graphics API 
Don't require a dest rect for now. Rendering is always at (0, 0) but
with the transformation applied. And the size shall for now not be a
parameter.

bbc4c508f9 Minor cleanup 
Replace lyon's rect import, which is a re-export of euclid's Rect<f32>,
with our own. Only the Path is
lyon specific, for now.

33dd2d765d Minor cleanup in item transform calculation 
We can use the new geometry() getter to simplify the transform update by origin.

4d26fe6674 Implement support for selecting the font family and pixel size in the GL renderer 
The public API in the properties is still missing.

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.

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

later.
