Friedemann Kleint ecb6327762 QTestLib: Introduce initMain() to run in main before qApp exists
When running Qt autotests on a developer machine with a high
resolution, failures occur due to either some widget becoming too
small, some rounding fuzz appearing when Qt High DPI scaling is active,
or some test taking screenshots failing to deal with device pixel
ratios != 1 in the obtained pixmaps.

It is not feasible to adapt all tests to pass on high resolution
monitors in both modes (Qt High DPI scaling enabled/disabled). It
should be possible to specify the High DPI setting per test.

Previously, it was not possible to set the Qt High DPI scaling
attributes since they must be applied before QApplication
instantiation.

Enable this by checking for the presence of a static void initMain()
function on the test object and invoking it before QApplication
instantiation.

Prototypically use it in tst_qtimer and to turn off High DPI scaling for
tst_QGL.

[ChangeLog][QtTestLib] It is now possible to perform static
initialization before QApplication instantiation by implementing a
initMain() function in the test class.

This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.

Linux X11:

   * The user must be logged in to an active desktop; you can't run the
     autotests without a valid DISPLAY that allows X11 connections.

   * The tests are run against a KDE3 or KDE4 desktop.

   * Window manager uses "click to focus", and not "focus follows mouse". Many
     tests move the mouse cursor around and expect this to not affect focus
     and activation.

   * Disable "click to activate", i.e., when a window is opened, the window
     manager should automatically activate it (give it input focus) and not
     wait for the user to click the window.
