title: Zoom in a canvas using canvas.scale function?
body: <p>I have implemented a long <code>onDraw</code> method which draws a set of rectangles. The rectangles are too small and I want them to appear bigger. But unfortunately I can't change the rectangle coordinates because they are stored in a database. So is there any way I can zoom in the canvas using <code>canvas.scale()</code> ?</p>
