Drawing doesn't start on mouse click on most browsers

[manuhabitela]

When you click on the board to draw without moving, a dot should be drawn.
Only Firefox seems to behave like this. Other browsers only start drawing on mouse move.

For some reason on the demo page (http://leimi.github.io/drawingboard.js/) it works fine

This bug seems to have something to do with css margins. When I added

margin: 0 auto;

to the drawing boards selector, the bug stopped for me when using Chrome.
