No minimize, that would be something custom I do later on (for example, for the O5 Command game). Close should definitely be allowed, as well as toggling ability to move the window.
[x] optional feature, on by default: do not allow title to get larger than would fit in the title
[ ] optional minimize button: requires a reference to what to minimize to
NO make this a custom extra for this lib (note: should probably work using excludeDraw? note that that would mean a selectable but unseen element, bad, make sure excludeDraw elements are not selectable in handlers!)
[x] optional: close button, on by default: deletes self
getTitleColor()
)
