282fa84789 Added support for optionally calling releaseContext at the end of each 
renderinTraversals() to help with cases where uses are driving multiple
contexts from mulitple viewers in a single threaded frame loop.

e09e07d45b Added support for assigning GraphicsContext to individual GUIEventAdapter events, 
and use of this within osgViewer::View to better track the sources of events.

7b003b24ea Refactored DatabasePager and related classes to introduce support for 
multi-threaded paging, where the Pager manages threads of reading local
and http files via seperate threads.  This makes it possible to smoothly
browse large databases where parts of the data are locally cached while
others are on a remote server.  Previously with this type of dataset 
the pager would stall all paging while http requests were being served,
even when parts of the models are still loadable virtue of being in the 
local cache.

Also as part of the refactoring the DatabaseRequest are now stored in the
ProxyNode/PagedLOD nodes to facilitate quite updating in the cull traversal,
with the new code avoiding mutex locks and searches.  Previous on big 
databases the overhead involved in make database requests could accumulate
to a point where it'd cause the cull traversal to break frame.  The overhead
now is negligable.

Finally OSG_FILE_CACHE support has been moved from the curl plugin into
the DatabasePager.  Eventually this functionality will be moved out into
osgDB for more general usage.

bc406c8bf0 From Jean-Sebastien Guay, " 
The problem can be reproduced by simply changing the osgpick example to
use a CompositeViewer with a single view initialized using
setUpViewAcrossAllScreens(). I have attached a modified osgpick.cpp so
you can test it out quickly (please don't check this file in though :-)
) The eventState is then incorrect and picking does not work. The only
changes are in CompositeViewer.cpp (eventTraversal() method), and fix
the problem for me.

caeed02f52 Merged the threading set up and rendering code from Viewer and CompositeViewer 
into ViewerBase to allow CompositeViewer to inherit the same theading models
previously just supported by osgViewer::Viewer

e5a365afee Added support for an update OperationQueue to Viewer and CompositeViewer to allow asyncrnous adding of operations to be added 
to the view to be done during syncronous updateTraversal().

This feature can be used for doing things like merging subgraphs that have been loaded
in a background thread.

27a1406819 From Blake Williams, "I discovered why the \u2013CompositeViewer option for the osghud example does not work. The run() function adds a camera manipulator to each view that does not have one assigned, which causes the view with the HUD camera to point somewhere other than where it should. I just added a check before a new default camera manipulator is added to ensure that the view allows event focus before a camera manipulator is added." 2007-05-26 15:47:53 +00:00
