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.

270c626c6c Make the Parser a trait 
Because the rowan::GreenNode is read-only but i want to use the parser
to generate something that can be mutated

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

8b854c32c3 Add Text::font_family and font_pixel_size properties 
We can fine-tune the API, this works for now to change :-)

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

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.

f7dfb030a0 Improve shader setup code 
Determine the locations of the uniforms and attributes once instead of on every use.
This makes the code easier to read and faster.

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.

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.
