FontData class is a lightweight class describing system fonts.
A FontData to a Font is analogous to an ImageDescriptor to an Image.
A FontData class describes the following properties of a Font:
name
height
style: combination of SWT.NORMAL, SWT.ITALIC, and SWT.BOLD
The Font itself is resource-based, i.e., if you create it, you must dispose of it.
You can use FontRegistry to manage allocation and disposal of the fonts.
