There are no places on the image to store the information you want. An
image is made out of pixels - what is freferred as sub-pixels is the
ability to fill a pixel partially - not of subdividing a single pixel
into more than one shade of gray. Darw with the pencil tool instead
- you will notice the difference.
What I told you to do is to incresae the resolution of your image, so
that you get MORE pixels. That is, if you are working in a 800x600
image, use a 1600x1200 or even a 3200x2400 image to paint on (scaled
down to 25%) - Then if the GIMP gives you strange results due to the
painting happening on a zoomed out image, you write here, and the
GIMP-developers will see if it can be imporoved in the program.
