Research direction
Start by tracing the existing Image, GraphicsContext, Canvas, and Dialog canvas APIs mentioned in the issue. Clarify the required UIImage construction paths and offscreen painting behavior, then verify that drawImage accepts the resulting object in onpaint.
Written by the indexing model from the issue text.
Description
We should be able to create an UIImage() from an Image (and maybe from scratch or other objects), and getting a GraphicsContext from it so we can paint on it as an offscreen Canvas object. The UIImage should be able to be the fastest representation to paint an image on the screen.
E.g.
local img = UIImage(app.activeImage)
Dialog():canvas{ ...
onpaint=function(ev)
local ctx = ev.context
ctx:drawImage(img, 0, 0)
end
