I found it uncomfortable when drawing on screen:
y = margin + (i - 1) * lineheight
- wruza 6y agoy = 1 + ... if y is 1-based too (which feels even more uncomfortable). But it would be nice to have such functions out if the box: canvas.linear_index(x, y, stride) vbox.y1_for(margin, spacing, height, i) vbox.y2_for(margin, spacing, height, i) And then you have "integer at the center of a pixel" vs "integer at the top-left of a pixel" differences, which should be taken into account by these functions too. Stroke 1: y+0.5, y+height-1. Stroke 2: y+1, y+height-2. Fill: y, y+height. Pixel geometry is hard on its own.
