Title:
  defaultGridUnit unit test fails on hidpi screen

Status in ubuntu-ui-toolkit package in Ubuntu:
  New

Bug description:
  There's a test failure in tests/unit/tst_units

  tst_units: FAIL!  : tst_UCUnits::defaultGridUnit() Compared floats are not the same (fuzzy compare)
  tst_units:  Actual (units.gridUnit()): 16
  tst_units:  Expected (8.0f) : 8
  tst_units:  Loc: [tst_units.cpp(36)]

  My environment has the following setting

  > echo $GRID_UNIT_PX 
  16

  matching the 2x scale factor to accomodate my screen resolution.

  I'm not sure why the default needs to be tested considering it's
  different on every device... it should either be dropped or the
  "units" test needs to clear the environment variable before testing
  it.
