Examples:
  dtk drawrect
  dtk drawline -testLevel 0 -testIndex 0
  dtk drawrect -c 1 -f 1 -l 0 -i 0
  dtk drawrect --offscreen --noDump --delay
OPTIONS:
  -l, -testLevel: Test Level. Run all test levels if it is -1 or not set.
  -i, -testIndex: Test index. Run all test indexes if it is -1 or not set.
  -c, -testCount: Test count in a single frame. It needs to be supported by test case itself.
                  It will be 1 if it is not set.
  -f, -frame:     Test frames that affact test duration. It will be 1 if it is not set.
  -h, --help:     Give this help list)
  names:          Print all test case name.
  fullnames:      Print all test case name with testLevel and test indexs.
  offscreen:      It will not be shown on the screen.
  noDumnp:        It will not dump image(jpg) in /data/local/tmp/dtk_output/
  skipInitial:    It will Skip Initialization to capture a flame graph, It can only take effect in off-screen mode
  delay:          Delay 2s before running.
  all:            Run all test cases.
  coverage:       Manually call __gcov_dump before exit 0
  load:           Run CPU and Gpu load cases
