Title: Stride to be the number of aligned bytes in each row

I think stride means the number of aligned bytes in each row.
Many of servo source code use stride as the same meaning but there are some codes that do not meet this definition(width of each row).

This patch fixes such code so that 'stride's have the same idea.
