/*
* slow_draw - sleep a little bit between drawing operations
*
* METHOD
* This test is basically the same as the draw subtest, except that we sleep a
* little bit after each drawing operation. The goal is to detect problems
* that can happen in case a drawing operation is done while the machine is in
* some deep sleep states.
*
* EXPECTED RESULTS
* The pattern appears on the screen as expected.
*
* FAILURES
* I've seen this happen in a SKL machine and still haven't investigated it.
* My guess would be that preventing deep sleep states fixes the problem.
