Added two scenes that demonstrate conflation artifacts as described in
https://github.com/linebender/vello/issues/49. The first scene
demonstrates adjacent triangles and rects that belong to the same path
and use opposite winding.
The second scene demonstrates strokes with overlapping square caps
(these strokes are currently expressed as rects painted with the NonZero
fill rule).
A number of things were wrong:
* The args were missing to `run`
* The robust memory changes introduced uniformity errors
* `clear_buffer` is a todo for wgpu on wasm
* Some more time calls crept in
* Initializing both env_logger and console_logger fails
In addition, we conditionally opt the shaders into
`workgroupUniformLoad`, as that's available on wasm but not yet native.
Some of the things (args, uniformity errors) are important fixes. Other
things (clear_buffer, wUL being optional) are workarounds for wgpu
limitations and have TODO items to be removed when wgpu catches up.
Make async versions of the main library entry points, and invoke those from the with_winit example.
Right now this just prints the contents of the bump buffer before just running the fine dispatch, but it could apply conditional logic.
* Improve the svg parser
* Handle `opacity`
* Double the segments buffer
* Rotate the multiplication
This matches firefox's output, although it is contrary to my use
of 3d transformation matrices
* Double ptcl size
Seems to be required to show entire scene at 4k
* Move the vello crate to the root of the crate
* Add warning that README is work in progress
* Add newline in warning
* Move the unlicense into the shader folder
* Fixup wgsl-analyzer include paths
