Samuel Rødal 55fa3c189f Got rid of Map / Unmap events in favor of Expose event. 
Since change 2e4d8f67a8 the need for Map and Unmap events has
gone away, as now the Expose event is used to notify the application
about when it can start rendering.

The Map and Unmap events weren't really used except by QWidget to set
the WA_Mapped flag, which we now set based on the expose / unexpose.

Also guarantee that a Resize event is always sent before the first
Expose, by re-introducing an asynchronous expose event handler. Since
an expose is required before rendering to a QWindow, show a warning if
QOpenGLContext::swapBuffers() or QBackingStore::flush() if called on a
window that has not received its first expose.

README 

Qt is supplied with a number of example applications that have been
written to provide developers with examples of the Qt API in use,
highlight good programming practice, and showcase features found in each of
Qt's core technologies.


Documentation for examples can be found in the Examples section
of the Qt documentation.
