[FIXED] llTextBox can be used to bypass @sendchat and @sendchannel (leave @sendchannel as-is for now)
  -> Reported by Chorazin Allen

Move the shader to renderFinalize (and also stop doing that oopsie of writing to the buffer we were reading from)

Fixed minor UI disabling issue related to Touch/Edit of attachments + @showloc and @edit (=open) workarounds

Add additional sphere effects for the initial RFC release and make params tweenable for the fun of it

Split behaviour modifiers into global scope (impacts all of RLV or other objects) and local scope (modifies only the behaviour only on that particular object)

[FIXED] @setenv_XXX commands affect the local rather than edit environment when @setenv restricted and @setenv_daycycle was issued

[FIXED] Holding the @setenv restriction isn't preventing other objects from changing the environment settings

[FIXED] FIRE-30508: @setenv_XXX commands are non-functional when the shared environment is the currently selected environment

LLHUDObject has a lot of deriveds stored as LLPointer<LLHUDObject>, no-virtual destructor is unlikely to be cause of the crash, but might be related

following promotion of DRTVWR-482

LLVOAvatars and derived classes appear to be stored as LLPointer<LLViewerObject> in a lot of cases, so non-virtual ~LLViewerObject() might be triggered by LLPointer and end up not cleaning sInstances in some cases (animeshes specific?), thus causing broken pointers in sInstances.
