Draw Visualizer
by Amavect!

Plan 9's draw() function can be confusing.
This program helps explain what it does.

Click the dst image to draw Rectangle r.
Click the src image to move Point p.

Observe the result.


Point p is generally for sprite sheets.
Move Rectangle r if you want to move where the src is being drawn in dst.
