f2df9293a9 Fix the C++ build 
Remove the Optional from the evaluation context passing for property
evaluation. Unfortunately there are nullptr uses left on the C++ side,
that need to be replaced with passing through.

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.

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.

8b854c32c3 Add Text::font_family and font_pixel_size properties

4d26fe6674 Implement support for selecting the font family and pixel size in the GL renderer

8e8943b8fe Clean up texture atlas allocation code 
Let each atlas texture know its index, so that it can return the final
allocation result right away.

86eaf027d4 Implement glyph runs grouped by texture 
In order to support multiple font sizes, etc. we have to deal with the
fact that the glyphs for a string may not end up all in the same atlas
texture. Therefore splitting of glyph runs by texture is necessary.

This works but could be improved further by sharing the vertex arrays
and just re-binding to a different texture and drawing the run's
triangles by index.

66c91ef658 Prepare for supporting multiple glyph runs 
A glyphs primitive may end up requiring multiple draw commands in the future,
so prepare for that.

994d47a529 Shader module cleanup 
Move the specific shaders into the shaders module and then hide the Shader
type. It's not necessary to export it anymore.

9b9a29e03d Clean up glyph handling 
Avoid calling glyph_for_char twice for each character.
Instead do the conversion once explicitly. That needs to be done anyway for shaping.

ddf137221a Implement glyph rendering using atlas texturing 
This means duplicate glyphs are rendered only once and we store glyphs
in the atlas texture globally instead of a texture per text primitive.

3c2ad7b275 Add support for atlas textures in the GL renderer 
... and place images in there by default. This improves locality.

The atlasing is also needed for individual glyph rendering, which is
coming soon.
