Relative mouse movement in HTML5.
I'm (still) porting an old Macintosh game to HTML5 and JavaScript. The game is a Tempest clone.

The typical ways that I'...

Strange HTML5 Canvas drawImage behaviour.
I am writing some code that uses HTML5 canvas. Genereally it works well, but now I found a very strange behaviour. The weird thing is that it is consistent on different browsers, so must be that I understood the thing wrong... despite this the docs seem to say exactly what I do. Here is the code (it's an object method): MyCanvas.prot...
