brace yourselves: E WINDOW PHYSICS MODULE!

Browse Source 
if you have ephysics installed, a new module 'Physics' will be available under Look which provides some fun physics effects on windows such as:
*velocity based on drag direction/speed
*collisions
*gravity
note that the edges of the screen are considered boundaries, and so windows will bounce off or get stuck in them; you will have to drag a window out if it gets stuck because I've disabled physics effects in edge areas to both 1) prevent windows from sneaking past the screen limits and flying off into space 2) actually getting stuck to the point that you can't get them out

help needed!
