This commit changes gtk_extended_layout_get_desired_size() for per dimension variants. Furthermore this commit reverts the actions done in size-groups for now as it needs a different approach. The natural width/height parameters added to aux_info have been changed for a per width cache for heights and a per height cache for widths. gtk-demo is still working, currently sizegroups are not taken into account as mentioned above - size groups need to be alerted both when the widths and heights are updated independantly and then that information needs to repropagate also to other extended layout implementors.
