* | Direct2D QPA: Disable vsyncLouai Al-Khanji2014-04-251-1/+1
| | | | | | | | | | | | | | | | | | We shouldn't block the whole gui thread for vsyncing. This can slow things down a lot if a lot of drawing happens.

* | Direct2D QPA: Fix text drawing with brush but no penLouai Al-Khanji2014-04-161-2/+2
| | | | | | | | | | | | | | | | | | We were incorrectly bailing out early in the text drawing code when there was no pen. This is incorrect as drawing with only a brush should be possible.

* | Direct2D QPA: Refactor code to reduce code duplicationLouai Al-Khanji2014-04-161-102/+120
| | | | | | | | | | | | | | | | | | Refactor duplicate logic in painterPathToPathGeometry and vectorPathToID2D1PathGeometry into one utility class. At the same time make the naming of the two functions consistent with each other. Change-Id: I03c8fc183863473b7337223e51835cf080914a41 Reviewed-by: Friedemann Kleint <Friedemann.Kleint@digia.com>

* | Direct2D QPA: Improve gradient supportLouai Al-Khanji2014-04-161-10/+87
|/ | | | | | | | | This change adds support for those gradients which can be expressed using Direct2D. At the moment this means linear and radial gradient with pad spread only. Change-Id: Ib1b1bc38a793dd826a259bbf8a7b31c25906dd59 Reviewed-by: Friedemann Kleint <Friedemann.Kleint@digia.com>

| | | | | | | | | | | | Changed clip rectangle handling from bounding rect to region. Now also sub region rectangles are taken in to account.

* Move Direct2D paint engine on top of QPaintEngineExLouai Al-Khanji2014-01-313-468/+531
| | | | | | | | | | | | | | | | | Make QWindowsDirect2DPaintEngine a subclass of QPaintEngineEx instead of QPaintEngine like the other paint engines inside Qt. This should both be faster and better supported, as the code paths handling QPaintEngineEx in QPainter are tested more. Additionally the visual output is closer to the raster engine, as all primitives are drawn using the same mechanism, resulting in fewer off-by-one-pixel errors. This change also makes designer work mostly correctly, apart from some remaining clipping bugs.

* Improve direct2d backing store implementationLouai Al-Khanji2014-01-277-166/+288
| | | | | | | | | | | | | | | | | | | | | | 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.
