The default implementation returns -1. Subclasses that support baseline should override appropriately. If a value >= 0 is returned, then the component has a valid baseline for any size >= the minimum size and getBaselineResizeBehavior can be used to determine how the baseline changes with size.
Returns: the baseline or < 0 indicating there is no reasonable baseline
Parameters:
- c - Component baseline is being requested for
- width - the width to get the baseline for
- height - the height to get the baseline for
Throws:
- IllegalArgumentException - if width or height is < 0

The default implementation returns BaselineResizeBehavior.OTHER, subclasses that support baseline should override appropriately. Subclasses should never return null; if the baseline can not be calculated return BaselineResizeBehavior.OTHER. Callers should first ask for the baseline using getBaseline and if a value >= 0 is returned use this method. It is acceptable for this method to return a value other than BaselineResizeBehavior.OTHER even if getBaseline returns a value less than 0.
Returns: an enum indicating how the baseline changes as the border is resized
Parameters:
- c - Component to return baseline resize behavior for
