GtkFontSelection in 1.3

[Robert Brady <robert susu org uk>]

GtkFontSelection in 1.3 appears to be a bit broken at the moment. To
reproduce :

 1. run testgtk
 2. choose the fontselector
 3. choose a smaller point size
 4. note the preview stays the same
 5. choose a large point size
 6. note the preview changes to the size you chose in step 3.
 7. choose a smaller point size
 8. note the preview changes to the size you chose in step 5.

and so on.

Don't know what's going on, but I found a workaround - adding an extra
gtk_font_selection_update_preview call to gtk_font_selection_load_font.
