Quick3D Texture elements require some window signals to show QML item as texture, so we fake them to make textures appear in form editor and state preview. To prevent texture mirroring, flipV value is force set at proxy creation. To keep state preview up to date, we trigger multiple render passes if there are any QML items used as texture sources in quick3D textures.
