Sorry, I understood you and it was me who was not clear. The problem is if I
go with 3×2 or 2×3, then I get 8 whole tiles, then the last frame has only 2
tiles, and I can not detect if draw_blank_frame() fails to draw on the
second line; with 2×3, I also fail to see if draw_blank_frame() has a
problem to draw partial lines. Same problem with 2×4, 4×2, 3×4 or 4×3: the
problem is that there are 50 input frames, 50 = 48+2, and 48 has a lot of
small factors. The first interesting possibility would be 3×5, but it's
starting to make large tiles, and too few whole ones.

Like you, I do not think there is a risk a problem happen with width and
height.

Regards,
