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.

Destroy render loop when QCoreApplication is cleaned up.

2014-03-29T06:35:29+00:00

Doing it on 'aboutToQuit' meant we would clean it up whenever an
application ran QCoreApp::exec() which could be multiple times
per application run.

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.

Unset the current gl window when deleted

This does in the QSGGuiThreadRenderLoop what 403045a did for the
QSGThreadedRenderLoop. Fix a memory corruption in Mesa's dri2 EGL
when setting a window current after deleting the previous current
one.

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.

introduced proper revisioning on the new signals.

[Changelog][QtQuick] Added QQuickWindow::afterSynchronizing(),
