 * This test suite currently works by building a quite complex hierarchy of
 * objects in a variety of styles and then performs a limited number of tests
 * for the previous and next dialog group or tab items.
 *
 * The test specifically does not test all possibilities at this time since
 * there are several cases where the Windows behaviour is rather strange and
 * significant work would be required to get the Wine code to duplicate the
 * strangeness, especially since most are in situations that would not
 * normally be met.

/* Tests
 *
 * Tests 1-8 test the hCtl argument of null or the dialog itself.
 *
 *   1. Prev Group of null is null
 *   2. Prev Tab of null is null
 *   3. Prev Group of hDlg in hDlg is null
 *   4. Prev Tab of hDlg in hDlg is null
 *   5. Next Group of null is first visible enabled child
 *      Check it skips invisible, disabled and both.
 *   6. Next Tab of null is first visible enabled tabstop
 *      Check it skips invisible, disabled, nontabstop, and in combination.
 *   7. Next Group of hDlg in hDlg is as of null
 *   8. Next Tab of hDlg in hDlg is as of null
 *
 * Tests 9-14 test descent
 *
 *   9. DS_CONTROL does not result in descending the hierarchy for Tab Next
 *  10. DS_CONTROL does not result in descending the hierarchy for Group Next
 *  11. WS_EX_CONTROLPARENT results in descending the hierarchy for Tab Next
 *  12. WS_EX_CONTROLPARENT results in descending the hierarchy for Group Next
 *  13. WS_EX_CONTROLPARENT results in descending the hierarchy for Tab Prev
 *  14. WS_EX_CONTROLPARENT results in descending the hierarchy for Group Prev
 *
 * Tests 15-24 are the basic Prev/Next Group tests
 *
 *  15. Next Group of a visible enabled non-group control is the next visible
 *      enabled non-group control, if there is one before the next group
 *  16. Next Group of a visible enabled non-group control wraps around to the
 *      beginning of the group on finding a control that starts another group.
 *      Note that the group is in the middle of the dialog.
 *  17. As 16 except note that the next group is started with a disabled
 *      visible control.
 *  18. As 16 except note that the next group is started with an invisible
 *      enabled control.
 *  19. Next Group wraps around the controls of the dialog
 *  20. Next Group is the same even if the initial control is disabled.
 *  21. Next Group is the same even if the initial control is invisible.
 *  22. Next Group is the same even if the initial control has the group style
 *  23. Next Group returns the initial control if there is no visible enabled
 *      control in the group. (Initial control disabled and not group style).
 *  24. Prev version of test 16.
 *      Prev Group of a visible enabled non-group control wraps around to the
 *      beginning of the group on finding a control that starts the group.
 *      Note that the group is in the middle of the dialog.
 *
 * In tests 25 to 28 the control is sitting under dialogs which do not have
 * the WS_EX_CONTROLPARENT style and so cannot be reached from the top of
 * the dialog.
 *
 *  25. Next Group of an inaccessible control is as if it were accessible
 *  26. Prev Group of an inaccessible control begins searching at the highest
 *      level ancestor that did not permit recursion down the hierarchy
 *  27. Next Tab of an inaccessible control is as if it were accessible
 *  28. Prev Tab of an inaccessible control begins searching at the highest
 *      level ancestor that did not permit recursion down the hierarchy.
 *
 * Tests 29- are the basic Tab tests
 *
 *  29. Next Tab of a control is the next visible enabled control with the
 *      Tabstop style (N.B. skips disabled, invisible and non-tabstop)
 *  30. Prev Tab of a control is the previous visible enabled control with the
 *      Tabstop style (N.B. skips disabled, invisible and non-tabstop)
 *  31. Next Tab test with at least two layers of descent and finding the
 *      result not at the first control.
 *  32. Next Tab test with at least two layers of descent with the descent and
 *      control at the start of each level.
 *  33. Prev Tab test with at least two layers of descent and finding the
 *      result not at the last control.
 *  34. Prev Tab test with at least two layers of descent with the descent and
 *      control at the end of each level.
 *
 *  35. Passing NULL may result in the first child being the one returned.
 *      (group test)
 *  36. Passing NULL may result in the first child being the one returned.
