Okay so like the PaintBrush would be gambas version of the fillStyle or
strokeStyle style

I think it'll be okay , image patterns was the next task, currently got
gb.integer CSS and gradient , 3 out of 4 is cool :)
going to handle images by using either src URL's or existing loaded img
objects.
Will look into making what i've done so far work your way through the
Paint.class

By the way, I don't think we should support CSS color names in Paint.

I think it's cool, we could add in documentation that it's down to the
programmer to use correct names if using CSS as they are not checked for
validity.
gotta love the option :)
