/**
 * Create an awt font by converting as much information 
 * as possible from the provided swt <code>FontData</code>.
 * <p>Generally speaking, given a font size, an swt font will 
 * display differently on the screen than the corresponding awt 
 * one. Because the SWT toolkit use native graphical ressources whenever 
 * it is possible, this fact is plateform dependent. To address 
 * this issue, it is possible to enforce the method to return 
 * an awt font with the same height as the swt one.
 * 
 * @param device The swt device being drawn on (display or gc device).
 * @param fontData The swt font to convert.
 * @param ensureSameSize A boolean used to enforce the same size 
 * (in pixels) between the swt font and the newly created awt font.
 * @return An awt font converted from the provided swt font.
