cbc43841e1 From Roland Smeenk, "this submission adds a "Fast Drawable" line to the camera scene statistics.
It shows the total number of sorted and unsorted drawables that use the fastpath for rendering."

7c38643a77 From Tim Moore, "I noticed that the "Materials" statistic in the camera scene stats display seemed to be identical to the number of drawables. In fact, it displays the nummat member of osgUtil::Statistics, but that variable has nothing to do with materials. nummat tracks the number of matrices associated with Drawable objects in a RenderBin; as I understand it, Drawables pretty much always have a model-view matrix tied to them in RenderBins, so this statistic doesn't seem very useful. So, I added statistics for the number of StateGraph objects in RenderBins and also for the number of Drawables in the "fine grain ordering" of RenderBins. The latter corresponds to the number of Drawables in the scene that are sorted by some criteria other than graphics state; usually that is distance for semi-transparent objects, though it could be traversal order. These two statistics give an idea of the number of graphic state changes happening in a visible scene: each StateGraph implies a state change, and there could be a change for each sorted object too. You can also subtract the number of sorted Drawables from the total number of Drawables and get an idea of how many Drawables are being drawn for each StateGraph.

0669107287 From Roland Smeenk, "While working on the Collada plugin I noticed that all geometry created by the dae reader result in slow path geometry.
Because there already exists the option to convert slow path geometry to the fast path by computing an internal fast path alternative, I added a new optimizer option that automatically does this. To check the results I also made some changes to the statistics gathering and rendering.

Somewhat unrelated, but also part of the optimizer I disabled removal of CameraView nodes during RemoveRedundantNodes optimization.
As discussed on the ML, CameraViews were removed from the scenegraph. This solves that issue.

Summary:
-Geometry::areFastPathsUsed now also looks at internalOptimizedGeometry
-Added Optimize option to make all slow path geometry compute their internal fast path alternative
-Added fast geometry counter to the statistics
-Disabled removel of CameraViews in optimizer
