More problems with RasterizeCameraTransform

[Frank C. <dev...@ch...>]

Got a few problems with RasterizeCameraTransforms:

1). The docs say "Any geometry type or rendering state may be submitted  
while this transform is active" but meshes with Z depth don't render  
(you just get a very thin cross-section). I think this is normal since  
the depth is limited, but the documentation is a little misleading.  
e.g. You can't submit a sphere and expect useful results...

2). Objects are displayed upside down and backwards. Billboards can be  
easily fixed with some UV twiddling but I'm not sure this is the  
intended behaviour. To get the top/left coordinate system it's  
necessary to flip the view, so I'm not sure if much can be done about  
this.

3). Picking doesn't work - looks like picks occur in world space, as if  
the rasterize transform wasn't there.

I'm pretty sure #3 is a genuine bug, but are #1 and #2 expected  
behaviour? If they are, the documentation should probably be more clear  
on how these transforms work.

I'll post bug reports over the weekend if warranted, but if someone can  
clarify whether or not these are real problems I'd appreciate it. I  
reported another rasterize bug earlier as well:

Thanks,
