[sldev] force object redraw?

[Dave Parks]

In order for a drawable to be picked up by the render pipeline, it has 
to pass the occlusion and frustum culling checks (meaning it must exist 
in a spatial partition) and have valid geometry to draw.  The call to 
markRebuild merely adds it to a queue to be prepared to be drawn, but 
does not actually cause it to be drawn.  markRebuild should only be 
called if the base geometry of the object has changed (like on an LOD 
switch).  The functions in LLPipeline you are looking for are 
"updateCull" (figure out what's visible), "stateSort" (last minute 
preparation for rendering, optimization of render call ordering), and 
"renderGeom" (running through the various drawpools and issuing OpenGL 
drawing commands).
