Is there a way to change the origin of the y-axis from the top to the bottom, with the positive being on top and negative on bottom?

Also, I notice that exact pixel coordinates are split down the center of the actual pixel. When I hover the mouse over a pixel, it will only show the correct coordinate of that pixel in the top left quadrant of that pixel. The attached picture represents a single pixel at (0,0). If I put the mouse over the red quadrant, I correctly get (0,0). If I put it over the Blue quadrants, I get (1,0) and (0,1). The Green displays as (1,1). This is rather inconvenient for me, as I'm working on pixel art, so I always have to make sure to mouse over the top left 1/4th of the pixel that I'm trying to find the coordinate of.

None I know of, unfortunately

Although I think I understand why it works this way, that could be seen as a bug since one result is that on a 2px wide image you'll see pixels at coordinates 0, 1, and 2. You can report it on bugzilla.gnome.org.
