Fix issue in which axis label would overflow outside of chart's bounding box. Added attribute allowContentOverflow (defaults to false) to toggle whether or not the layout algorithm will allow for the old behavior. Fixes #2531003

Removed explicitWidth/explicitHeight. Now setting width/height on axis will work.

Removed extraneous axis layout methods.

Add explicitWidth and explicitHeight to axes.

Added Shape groups to graphics. Added notion of groupMarkers to charts to allow for high performance rendering a large number of markers in a single chart. More axis performance optimizations. Added drawCircle, drawEllipse and drawDiamond to VML and SVG drawing engines. Optimized shape getBounds method to use newly created matrix.getContentRect method.

Chart axis labels use matrix for rotation and positioning. Minor vml optimization. Add getRectBounds to Matrix class.
