What do you think about the following point?

(Maybe "pixel" above should be "unit".)
One can argue that the new API can return enough information to deal
with the scale factor by computing width and height in both relative
and absolute coordinate systems. But I guess many programmers just
tends to add some offsets for the conversion between these coordinate
systems. This might cause rewrite of elisp programs when GTK+
supports resolution independence in future.
