Step #1: Create a new image with a white background (any size will do)
and zoom in to the upper left corner.
Step #2: Open the Script-fu console and enter the following commands
(the number "1" in the first line assumes the new image is the first one
created after opening the GIMP; substitute the appropriate image-IDnum
from the window's titlebar if this is not the case):
(define image 1)
(define layer (car (gimp-image-get-active-layer image)))
(gimp-drawable-set-pixel layer 1 1 3 (cons-array 3 'byte))
Note that at this point, the pixel at location x=1, y=1 has "internally"
been painted BLACK ('cons-array' initializes to [0,0,0]) but the display
has not been updated.
Step #3: Enter the following line in the console:
(gimp-displays-flush)
Note that the display is not updated -- this is somewhat anomalous (but
then Script-fu is not often used to paint on a pixel-by-pixel basis).
Step #4: Hide and then unhide the layer by toggling its "eyeball" in the
Layers window. At this point the projection is updated to reflect that
the pixel at [1,1] has been painted black.
