programmatic mouse click

Yep the events could definitely use some documentation!

As to

use coordinates in data space as opposed to pixel space

data_space_point = Makie.project(ax.scene.camera, :pixel, :data, pixel_space_point)

that's close, thank you! but, there seems to be a translation problem that needs to be subtracted. if i plot three points as follows, and then put my cursor directly over [1,1] in data space, project returns (1.18,1.19). similarly, [2,2] returns (2.18,2.20). where is the ~0.2 offset coming from?

julia> using GLMakie

julia> fig,ax,s = scatter([1,2,3])

you need to subtract the ax.scene.px_area[].origin from mouseposition[] I think

[bjarthur]

that works, thanks! though px_area has been renamed to viewport:

┌ Warning: `.px_area` got renamed to `.viewport`, and means the area the scene maps to in device independent units, not pixels. Note, `size(scene) == widths(scene.viewport[])`

Right, years old habits ;)
