Just a quick follow-up; Mario's quite right that you use the 
Window#paint method to acquire a DeviceContext to do drawing. It is 
recommended that this is within an evt_paint handler which means that 
drawing will only be done when necessary. The sample image/images.rb is 
probably the simplest example to look at.

However, there isn't a "draw" method as far as I know. "paint" is used 
in all circumstances, but the exact type of DC will be different 
dependent on the, um, context. But there will be no functional difference
