Rotating Shapes with a Transform in SVG

Since these shapes are pretty straightforward, I've added a transform to the next one to make things interesting. In SVG a transform refers to the geometric kind; a translation (movement), rotation, scale, or skew (shear). I'll just explain the transform I've used for now and maybe I can expound on it more at a later date. The transform used here is described where the source reads transform="rotate(-45 100 100)". This means that the rectangle should be rotated 45 degrees counter-clockwise with the center of rotation at (100,100). Other valid transformations are matrix, translate, scale, skewX, and skewY. You can read more about these in the specification if you're interested.
