Threaded render loop should block until the frame is swapped.

Introduced the concept of an expose cycle, as the WM_Expose
is followed by WM_RequestSync and only after we handled the
sync and then swap, should we unlock. Otherwise, we are
potentially waiting for the wrong swap.

This also fixes a bug when we get an expose while the render
thread is animating on its own. We would previously set
RequestRepaint, but this could potentially be reset by a render
thread animation if the GUI thread took a short while getting
to the point where it sent the RequestSync. If that requestsync
did not result in SG changes, we would not render anything.
With the exposeCycle, we are now guaranteed to repaint after
we handled the sync, which is how it should be.

Fix renderType: Text.NativeRendering on retina screens

The QSGDefaultGlyphNode's QSGTextMaskMaterial failed to take the device
pixel ratio of the surface into account, both when building the glyph
cache in init() and when blitting the glyphs from the cache in populate().

We now handle both, resulting in equal rendering as the raster engine,
which itself matches CoreText, except for some minor shaping differences.

One snag with the QSGTextMaskMaterial compared to eg. the raster engine
is that the incoming glyph positions (from shaping) are not pre-scaled,
which means we have to be careful to apply the device pixel ratio before
rounding the coordinates, to match the behavior of the raster engine.
