* Delay the deletion of QSGTextures until all windows are synchronizedDominik Holland2017-06-165-0/+26
| | | | | | | | | | | | | | | | With the 'basic' and the 'windows' render loop the scene graph context is shared. Because of this we cannot start deleting textures after the first window is synchronized as it may contain textures needed by the another window, which is not yet synchronized. QWindowPrivate::syncSceneGraph() is not calling endSync() anymore as it doesn't know whether it is the last window or not. Instead the renderloop is now responsible for calling endSync() once this is safe to do.

* Improve dirty region calculation in software rendererJüri Valdmann2017-05-233-36/+55
| | | | | | | | | | | | | | | | | | | | | The software renderers dirty region calculation is done in integral logical coordinates, which leads to quite some trouble when handling scene graph elements with fractional coordinates (used by WebEngine for example). The optimal solution would probably be to either use integral physical coordinates or floating point logical coordinates, however this would seem to require substantial changes to QPainter and QBackingStore and so on. So, this patch instead changes the calculation to use something like interval arithmetic: instead of just rounding each logical coordinate to the nearest integer the renderer now uses (very carefully) both the upper and lower boundaries to make sure that the dirty regions always err on the side of caution. I expect this change to make rendering slower but only in situations where previously there would be rendering errors.

* Add a method to query the scene graph backendMichael Brüning2017-04-272-0/+10
| | | | | | | | | | | | | | | | Since 5.8, it has been possible to set the scene graph backend using QQuickWindow::setSceneGraphBackend instead of using the environment variables. This caused some trouble with modules that need to know which backend is used and relied on the environment variables or command line options for getting this information. One example of such a module is Qt WebEngine, which crashed because it ended up trying to use OpenGL resources with the Qt Quick scenegraph software backend.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The software render loop updates the window content via either an expose event or an update event. An expose event should always flush the entire backingstore, but previously only the newly updated region would be flushed. The first time a window is exposed this is fine because the whole scene would be rendered, but when hidden and shown again, the software renderer might show that nothing has changed, and nothing would be flushed. A new flag has been added that forces a full window flush for an expose event.

Should be feature complete now, but there are still some issues that could be improved in future commits: If Rectangle nodes are rendered with a non-affine transform, they will be rendered incorrectly. This is because paths expect affine transformations. The Glyph cache is a bit cheeky in that it's caching paths, but doing so per font size. It shoudln't need to, but right now I've not though up a good way of getting the transform/scale needed when rendering yet.
