Add to tooltips?

[Daniel Egger t-online de (Daniel Egger)]

Hi developers,

 I'm planning to expand the possiblities of the tooltipssystem
 including:

 -Better layout
 -More features
 -More configurability

 To accomplish that it would be nice to have another entry 
 in the tooltip struct which gives the possibility to set some flags
 just as: JUSTIFY_LEFT,JUSTIFY_CENTER,JUSTIFY_RIGHT,
 LAYOUT_LEAVE,LAYOUT_OPTIMIZE.

 But just adding a guint to GtkTooltips will cause binary incompatibilities,
 I'm afraid.

 So any ideas and/or hints how to work around are welcome.
