Directly handling primitives is faster than using the catch-all fill
function which converts arbitrary paths into a direct2d geometry. So do
so.

Aliased drawing has so far not been perfectly pixel aligned, resulting in
less than stellar output in some instances. Although a little hacky,
adding 0.5 to all coordinates when in aliased mode fixes things up nicely.
There doesn't appear to be a better way to get d2d to cooperate as we
would like it to.

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 the way we fall back to the raster engine by forwarding painting
state. Amongst other things this makes perspective transforms appear
correct.

Use axis aligned clips when possible instead of layer-clipping. This can
be much faster when a lot of clipping operations take place.

We shouldn't block the whole gui thread for vsyncing. This can slow things
down a lot if a lot of drawing happens.

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.

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.

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.

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.

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.
