[New-bugs-announce] [issue42992] Tkinter bbox coordinates incorrectly drawn

[Ron Hoffmann]

New submission from Ron Hoffmann <rhoffmann at muskokawoods.com>:

position coordinates retrieved from any object on a canvas with
pos = canvas.bbox(object) are returned correctly

but when drawn on the canvas (x0,y0) are correct, but
(x1, y1) are not drawn in the proper positions. x1 has been divided by 2 somewhere and y1 as been multiplied by 2 somewhere.
in order for the bounding box to be drawn correctly
x1 and y1 need to be recalculated as follows

x1 = pos[0] + ( ( pos[2] - pos[0] ) * 2 )
y1 = pos[1] + ( ( pos[3] - pos[1] ) / 2 )
