[sldev] force object redraw?

[Anna Gulaev]

These are drawables that have already been rendered, and updateCull,
stateSort and renderGeom are being called after these objects are modified.
Still, changes to them are not rendered until they are selected (by
right-clicking them).

For example,

object->mDrawable->setState( LLDrawable::FORCE_INVISIBLE);

has no immediate effect, though updateCull, stateSort and renderGeom all
happen repeatedly (with every frame, I believe) after this change. I've made
appropriate changes to llviewerobject, llviewerobjectlist and pipeline to
ensure my changes aren't being undone, and am pretty certain they aren't
given that the changes take effect when I select the objects.

Through markRebuild, setChanged and updateDrawable I've managed to get the
objects to re-render sooner-than-never (with some crashing), but I haven't
found a way to get them to render immediately, or even, say, within 10
seconds.

That is, I've set a lighthouse invisible but can still see it. I can look at
it as long as I like, turn so it's out of my field of view and then back,
zoom in on it, etc, and it will not update. Right click it and *poof* it's
gone. I can't figure out how to make it *poof* immediately :-)

Thanks,
Anna
