Use global context sharing from QtGui instead of QSGContext

2014-04-04T11:49:51+00:00

This removes QSGContext::sharedOpenGLContext and replace its uses
with QOpenGLContextPrivate::globalShareContext, which is also going
to be used by QOpenGLWidget and QQuickWidget.

Fix potential crash during shutdown for QQuickWindows

2014-03-17T14:45:45+00:00

The cleanup() function would deregister the render loop from all
windows the render loop had seen, but the render loop doesn't see
windows until the window gets a showEvent and for some implementations
it was removed as a result of hideEvent. So add explicit tracking to
QSGRenderLoop which is managed by QQuickWindow's constructor and
destructor. With this, we no longer need the lists from the
subclasses, so these functions are removed again.

Make sure QSGRenderLoop is cleaned up cleanly.

2014-03-14T09:45:53+00:00

e13547c595913c58e6bd6a5ed80fdc729fae7d47 used a global static to clean
up QSGRenderLoop which is triggered very late, potentially after
SG backend API plugins have been unloaded. This results in crashes
when used in combination with scenegraph-playgrounds's customcontext.

Partially revert the change and instead clean up at the time of
QApp::aboutToQuit and make sure we also disconnect cleanly from
all QQuickWindows.

This change also ensures that QSGRenderLoop::windowDestroyed() gets
called for all QQuickWindows registered with the render loop. This
ensures that rendering stops and that scene graph nodes and resources
will be cleaned up regardless of whether the application has
remembered to delete the window or not. This is a good thing as it
makes the scene graph shutdown a bit cleaner.
