title: SWT: draw "icons" in table or tree cells
body: <p>We are having a Swing application which we plan to port to SWT/JFace. The Swing application draws a lot of icons (<code>javax.swing.Icon</code> implementations) in trees and tables (icon left to the text). If I understood it correctly, SWT only can draw <em>images</em> (aka graphic files). What would be the simplest solution to paint the icon or entire table/tree cell? Thanks in advance.</p>
