Title: Support for drawing/rotating triangles in IE8

Couple of changes that allow the following
- rotation now supports negative values (simply by translating to proper positive value)
- rotation now controlled by css styles
- protovis triangle shape can now be drawn properly
- above change should allow for any path with multiple coordinates to be drawn properly

Note, I have only used this change to draw triangles using protovis' .shape('triangle')
