| | | | | | | | | | | | This switches the font rendering to use gray scale antialiasing when in translucent rendering mode. It does so by adding a flags argument to the paint engine, allowing for future expansion in communicating render hints from the device to the engine.

* direct2d: Fix translucent/frameless window renderingAndrew Knight2014-09-011-35/+115
| | | | | | | | | | | | | | | | | | | | When using WA_TranslucentBackground/FramelessWindowHint, the backing store must paint to an offscreen texture instead of the swap chain in order to achieve the desired results. This texture is then presented to the screen using UpdateLayeredWindowIndirect(). As the swap chain is not needed in this mode, its construction is skipped if indirect rendering is active. Furthermore, the layering options were updated to fix an issue with transparent layers overpainting the background. The layer options were switched to D2D1_LAYER_OPTIONS1_NONE, which appears to work for both translucent and non-translucent rendering modes.

* Direct2D QPA: Draw directly to swap chainLouai Al-Khanji2014-05-051-18/+74
| | | | | | | | | | | | | | | | | | | Remove the intermediate pixmap in the backing store and draw directly to the window swap chain. This is faster and reduces memory pressure on the graphics card. In case of native child widgets we need to read back the back buffer, which incurs an extra copy in this case. In an artificial benchmark drawing animated full screen gradients as fast as possible this patch increases performance by 42% on my current machine from 480fps to around 680fps, i.e. the time for actually getting the pixels to the screen is now lower.

* Improve direct2d backing store implementationLouai Al-Khanji2014-01-271-0/+177
Add a per-window swap chain to a QPlatformWindow subclass instead of tying it to the backing store. This is needed to support native widgets (as opposed to alien widgets). Change the backing store to draw to an intermediate pixmap and flush to the requested window by using the per-window swap chain. This also opens the door for faster window presentation later on by using the swap chain more intelligently. Also add a changelog entry for the direct2d plugin, which was omitted earlier. [ChangeLog][QtGui][Windows] Introduce experimental direct2d platform plugin for Windows. This plugin shares most code with the current windows plugin, but substitutes a direct2d-based paint engine for window backing stores and pixmaps.
