Put snapshot related floaters always on top of the full screen preview.
Make having multiple running uploads more robust.
Fix infinite recursion when clicking on the bottom 'Snapshot' button
under certain conditions.
Unfreeze time more robust; unfreeze time out of precaution when
starting an upload (if 'Keep open' not checked).
Fixed a bug that caused all callbacks for successful feed uploads to be
ignored.
-Removed a few extra unneeded virtuals
-Pulled tabgroups out of llpanel and into LLView
-removeChild doesn't support delete. Delete manually.
-addChildAtEnd renamed to addChildInBack
-getScreenRect renamed to calcScreenRect
-added calcScreenBoundingRect and calcBoundingRect(which updateBoundingRect calls
-General cleanup. Someone at LL figured out that dynamic_cast actually exists.
Fixed PieMenu not reliably centering on cursor.
Fixed context menu crash in line and text editors.
Classes with LLEditMenuHandler as a base do not need to set gEditMenuHandler to NULL, since LLEditMenuHandler's dtor does that already!
It has happened to me that this hung the viewer. The cause is that
when you call parent->getParentFloater(child), then getParentFloater
which starts like this:
LLFloater* LLFloaterView::getParentFloater(LLView* viewp)
{
LLView* parentp = viewp->getParent();
starts with parentp == this. And the following logic causes
it to return 'viewp'!
I'm pretty sure that getParentFloater's whole design is wrong,
but I don't see another way to avoid this problem then with
this hack, except by making changes that do a lot more and
are a risk with regard breaking code elsewhere.
Added LLObjectList::getAvatar(LLUUID) for type-safe and quicker lookup
Added F32 overload to LLSD because using F64 needlessly is silly.
(And its lack of F32 overload caused issues with LLCachedControl<F32>)
