Fix tst_QWidget::translucentWidget() on high DPI displays

Browse Source 
It was grabbing a QLabel without accounting for the size of
the window in the case where the DPI is larger than 1:

FAIL!  : tst_QWidget::translucentWidget() Compared values are not the same
   Actual   (actual.size())  : QSize(32x32)
   Expected (expected.size()): QSize(16x16)
