daf23f8736 Pass the evaluation context through the binding closure 2020-05-28 09:20:11 +02:00

c4dd857e0d Add an evaluation context to property evaluations 
The context is not used yet or passed on to the binding closure.

50ecffe1f1 Replace RenderingInfo with RenderingPrimitive 
This is one data structure less and it avoids converting from the one to
the other.

bcc6c6a60a Move Color and RenderingPrimitive into abi::datastructures 
This paves the way to replace RenderingInfo.

230870a292 Style cleanup 
Remove some where clauses that leads to less verbose signatures. Also
use impl FnFoo, which is shorter as well.

d48faf711f Update cached rendering data only when there are changes 
This introduces a separate rendering preparation step in the main
window. As a consequence, the component becomes a parameter and the
graphicstest example can't use the main window anymore.

The decision whether a new low-level primitive needs to be created or
not is made by comparing the last RenderingPrimitive against the new
one.

On the upside, this means that property changes are now reflected in the
graphics.

cd80a4038f Clean up HasRenderingPrimitive trait API after transition 
The extraction does not have to be optional anymore. That will make
future code using this simpler.

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.

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!().
