Thiago Macieira b1fd9a93b9 Speed up tst_QGraphicsView::mapToScene test
This test is doing a brute-force mapping. Coupled with changes to
QCOMPARE last year, this now allocates and deallocates a lot of memory
per iteration. On my Sandybridge, it takes two minutes to run:

     111136.781153 task-clock                #    0.999 CPUs utilized
   371,692,633,238 cycles                    #    3.344 GHz
   182,641,818,708 stalled-cycles-frontend   #   49.14% frontend cycles idle
    57,951,552,830 stalled-cycles-backend    #   15.59% backend  cycles idle
   477,216,332,971 instructions              #    1.28  insns per cycle
                                             #    0.38  stalled cycles per insn
    86,959,637,669 branches                  #  782.456 M/sec
       309,185,237 branch-misses             #    0.36% of all branches

     111.264868818 seconds time elapsed

Changing the iteration step from 1 to 5 reduces the runtime to about 5
seconds.

This directory contains autotests and benchmarks based on QTestlib. 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.
