This PR implements a new
Canvaswidget iniced_wgputhat is capable of drawing 2D graphics with GPU rasterization by leveraginglyon.The widget can be found in the new
canvasmodule, alongside a bunch of other useful types for drawing and compositing layers. Check out the documentation to learn more!Overall, the public API is very similar to the
CanvasRenderingContext2Dof the Web Canvas API, although some of its functionality is still missing.I have also implemented MSAA support for the
Mesh2Dprimitive iniced_wgpu. This setting can be enabled with the newantialiasingfield inSettings.A
Canvassimply produces a set ofMesh2Dprimitives (see #140) when drawn. In the long run, we should try to help with nical/lyon#185 or use a more advanced rasterizer likepathfinder.Finally, I have created two new examples to showcase the
Canvaswidget:solar_system, a simple animated solar system showcasing how to compose different transforms.clock, an application that draws a clock and its hands to display the current time.
