* Update copyright headersJani Heikkinen2015-02-111-7/+7
| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <matti.paaso@theqtcompany.com>

* direct2d: Fix translucent/frameless window renderingAndrew Knight2014-09-011-3/+13
| | | | | | | | | | | | | | | | | | | | 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-Khanji2014-05-051-14/+28
| | | | | | | | | | | | | | | | | | | 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.

* Direct2D QPA: Speed up widget paintingLouai Al-Khanji2014-04-291-0/+10
| | | | | | | | | | | | | By only starting/ending drawing once in the backing store, we can avoid multiple start/ends and thus flushes of the direct2d device context. This can potentially be much faster with some drivers when many widgets that draw to the same backing store need to redraw. Because starts/ends of QWindowsDirect2DDeviceContext are already refcounted this works out of the box.

* Improve direct2d backing store implementationLouai Al-Khanji2014-01-271-152/+16
| | | | | | | | | | | | | | | | | | | | | | 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.
