At least some of us are very aware of the importance of placing things
exactly on the pixel-grid whenever possible. Still good to have an
explicit description of this issue as reminder.

In my example, I used rotated text and ovals to trigger anti-aliasing
issues and didn't care about the grid in the few places where I could
have. Things that line up with grid are less likely to gain anything
from exporting to larger size and down-sampling.
