* things to add:

|
||||
* * if a word spans 2 layout nodes with no whitespace, it should not be splittable.
|
||||
* * styles (outline, glow, etxra glow, shadow, soft shadow, etc.)
|
||||
* * add spacing/padding for style effects (first scan all format nodes and find styles, add up/merge padding), then do real layout.
|
||||
* * if a word (or char) doesnt fit at all do something sensible
|
||||
* * anchors (for inline objects other than text - images etc.) - variable size ones too
