fix: round canvas coordinates to nearest grid cell
Previously the canvas coordinates were rounded towards zero, which causes the rendering to be off by one pixel in some cases. It also meant that pixels at the extreme edges of the canvas can only be drawn if the point was exactly on the edge of the canvas. This commit rounds the coordinates to the nearest integer instead.
