+// * Canvas width/height should is using content-box by default. IE in
+// Quirks mode will draw the canvas using border-box. Either change your
+// doctype to HTML5
+// (http://www.whatwg.org/specs/web-apps/current-work/#the-doctype)
+// or use Box Sizing Behavior from WebFX
+// (http://webfx.eae.net/dhtml/boxsizing/boxsizing.html)
+// * Non uniform scaling does not correctly scale strokes.
