For reference let's try to stick to the last x_scale_font.diff patch I
sent you.  What was the "impair" size there?  Note in all theses cases:
The real size of a frame as it is displayed (or better cut off) by the
WM is only reflected in our pixel sizes.  The character sizes (including
those displayed by GNOME) are just approximations which reflect the
displayed sizes faithfully iff when multiplied by the character sizes
they result in the corresponding pixel size.

"impair" size every time I resized it with the mouse.

The present one or the one I sent you before?

Please send me the *foo* transcript.
