Unlike OpenGL, the EGL_SWAP_BEHAVIOR_PRESERVED_BIT was not set for

enabled still, which, according to the EGL spec, should fail. To
make sure it still works with other EGL implementations, the bit

QNetworkConfigurationManager creates the engines loaded from plugins
as objects in the main thread.
If a QNetworkConfigurationManager instance is created in a worker thread
without any instance previously existing in the main thread, then it
is uninitialised until the main thread has run.
This causes allConfigurations() to return an empty list if called
immediately after instantiation, for example.
This fix initialises the plugins using blocking queued connections,
which causes the worker thread to block until the initialisation function
has been called in the context of the main thread.
Deadlock is possible if the main thread is for some reason waiting on the
worker thread, but it will not deadlock on QNetworkConfigurationManager's
mutex.
If this is a problem for an application, it should use
QNetworkConfigurationManager from the main thread first to preload the
plugins.

gamma correction of text with a gamma of 2.1. On Mac this is
sufficient for gamma correcting subpixel antialiased text. Gray
antialiasing should not be gamma corrected on Mac.
On Windows, the user can potentially set the gamma value to anything
between 1.0 and 2.2 (or something like that). We support anything
that resembles 1.0 closely enough by pushing the text out without
any correction (like before). We also support anything that resembles
2.1 (the gamma hardcoded in GL's SRGB extension) by turning on the
extension before blending the text. In between the two, we'll use
gray antialiasing to avoid differing too much from the raster engine
(which is our reference in this.)
For gray antialiasing on Windows, we use a constant gamma of 2.3 which
has been determined by experimentation. Since this is close enough to
2.1 we do gamma correction with SRGB extension.
The distance limit of 0.2 is determined by some experimentation.

This will allow us to expose private headers in a controlled manner,
and ensure that they are not used by accident. This also means that
we internally will have to enable the private headers for the
modules we wish to use in the project.
startPolling() is called by each engine, so before it would start
multiple singleshot timers. So I moved the timer to the class
and check if it has already been started before it is activated
again. So that we just use one timer.
