On the left of the pencil is a 6 x 6 square. The pencil isn't right.

I was working on making a pixel art thing, where each "pixel" is 6 x 6 pixels.
But I ran into this issue.
In the toolbox I chose the pencil tool. Next, in the tool options I went the brush and picked pixel. Then I moved the size slider to 6. I started to use it, but realized that it was only drawing a 5 x 5 of pixels. I changed the size to 7, and it still was only 5 x 5 pixels. I changed it to 8, and it was 7 x 7 pixels.I have reproduced this. I tried restarting gimp, and re-installing it. No effect. It would be nice if this was fixed. Thanks!
