This plug-in runs creates a new image and every 0.3 second: it draws your current (paint)brush with current settings over a half-white, half-background-color background. You can leave the image opened and change to it any time to see your brush current state (don't close it, if you do, it just reports an error because well the process that draws can't find the closed image, then you'll have to run plug-in again to see it again). But leaving it opened is fine you can switch back and forth between images to view brush settings or work on your own image.
This will allow users to get a good feel of what their brush does when changing different settings and see it (drawn as horizontal line, vertical line, and a simple one click paint [in the center])
