I want to annotate an image with 2D keypoints. Inspired by the example in the readme, I am using the following script

Script

using MakieDraw
using GLMakie
using GeometryBasics
using FileIO

img = load("/home/nitin/Downloads/IMG_20230302_104301389.jpg");
figure, axis = image(rot180(img),axis = (aspect = DataAspect(),))


categories = Observable(Int[])
point_canvas = GeometryCanvas{Point}(; 
  figure=figure, axis=axis, properties=(; categories), mouse_property=:categories,
  scatter_kw=(; color=categories, colorrange=(0, 2), colormap=:spring)
)
categories[]

point_canvas.active[] = true

layers = Dict(
    :point=>point_canvas.active,
)

MakieDraw.CanvasSelect(figure, axis; layers)

Output

Clicking on the links in the README leads to a 404. We should fix that..

We should be able to show with the cursor if you can grab a line or vertex when you move over them with the mouse.

This should reduce a lot of confusion over what will happen when you click in a point.

When we draw polygons movement of points should stop at the point where a line would intersect another to create an incorrect polygon. We can probably use tools from GeometryOps.jl to do this once it has stabilized.
