Thanks a lot to Niran for assistance in this. Tooltips are from Black Dragon's machinima panel.
Note: Moves Depth of Field checkbox into the new Depth of Field tab.
Moves to calling refreshEnabledState directly from LLPanelDisplay instead of bouncing around in LLFloaterPreferences first or using static proxy functions
Cleans up unused cached button pointers and old style static callbacks.
Moves to visibility_control and enabled_control instead of using callbacks, this lightens the load on opening preferences, and makes them responsive even to debug settings changes
Removes the moving m for meter text with draw distance, I don't think anyone cares if it's a little to the side of the number.
Adjustment of tabs to spaces in xml.
Return early when disabling unavailable settings if shaders are unavailable.
Cuts back on single-call functions in favor of direct binds.
Cleans up some related code, probably looks nicer with space changes off.. though this is a pretty straightforward change.
Comments out code that still exists in xmls or might likely be added in future.
Each piece tested quite a bit.
Still not translated, left the old translated floaters for easier translation.
New Hardware Tab is work in progress, it should be more populated in the future, but is fine for now.
-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.
