I think drawPdf should leave the styling and scale of the pdf to the hook caller.
Setting the canvas height and width is fine for displaying the PDF since the canvas is taking on the height and width of the PDF. The canvas element that uses the hook can be styled in any fashion through class name or style.
This also provides a solution to #405.
Before this change, the scale was only applied to the pdfjs-generated viewport, this instead applies the scale to the canvas. Referenced from this SOF: https://stackoverflow.com/a/5306929/4771642
