Let`s say i want to achieve extremely space-efficient list views.
Let`s say i want CellRendererText to be $FONT_HEIGHT_MAX + 2
pixels high, so that no pixels are wasted at all.
How do i do this?
Ok, we have the "ypad" g_object property of the CellRenderer. And the
expected way to drop the wasted pixels is to set this property to zero.
And yes, it by default equals to 2 (which is a perfect default, but remember,
we go for extreme space saving).
However setting it to zero still leaves more than 5 pixels wasted for
no apparent reason.
Below is a test program which shows this problem. But it is not the
only one i`ve met on my quest.
Also its seems to be impossible to set the size of a cell renderer
below 10 pixels high. And this is very frustrating because given some
ultra small fonts this could be extremely cool. Think XMMS playlist
for example.

gtk_main();
return 0;
}
