Teleport height restrictions have been increased to 8192
-The 4096 limit isn't in much of the teleport code anyhow, and it's certainly not enforced.
Building height restrictions are now hooked up to hippolimits, apparently they hadn't been
-MAX_OBJECT_Z, and hardcoded 4096s now use gHippoLimits->getMaxHeight() instead
-On floater_tools.xml max_val is left out, instead it is set with the rest of the gHippoLimits edit constraints in LLPanelObject::getState
-Nametag bubble visbility is oddly inconsistent. May vanish with future planned UI merges...
-VBOs are PAINFULLY slow on ATI hardware. This repos self-compiled davep/shining-fixes branch, so I'll leave the ball in LL's court for now regarding that.
