@rsms yeah, font rendering is basically the only place this exists. Font hinting can be applied to nearly arbitrary graphics, but it does work best on "text-like" stuff. TTF hinting would be able to express the constraints on your example logo shape pretty well - it can do things like ensure that the whitespace gaps are an integer number of pixels, and that both gaps are the same width, align the tops and bottom of lines to pixels while constraining the width of line, etc.
