We don't use glitz or libpixman, so you don't need to worry about them.

You might as well call ddisplay_add_update_all(), if you do that,  Then
you won't have to run through the objects and combine their rects.  But
yes, I am worried about performance if you do that.  Once you get to a
couple hundred objects, you will get a hit from doing this, whether you
use the rects or not.

Why do you iterate backwards, BTW?

Thank you!  I can't rightly take any praise for the libraries we
incorporate, but thanks.
