* Make each steps for the tests in following arrays in global scope. Each item

*
* description:
* Set the description of the test. This will be used for the message of is()
* or the others.
*
* message:
* aNativeMessage of nsIDOMWindowUtils.sendNativeMouseScrollEvent().
* Must be WM_MOUSEWHEEL, WM_MOUSEHWHEEL, WM_VSCROLL or WM_HSCROLL.
*
* delta:
* The native delta value for WM_MOUSEWHEEL or WM_MOUSEHWHEEL.
* Or one of the SB_* const value for WM_VSCROLL or WM_HSCROLL.
*
* target:
* The target element, under the mouse cursor.
*
* window:
* The window which is used for getting nsIDOMWindowUtils.
*
* modifiers:
* Pressed modifier keys, 0 means no modifier key is pressed.
* Otherwise, one or more values of SHIFT_L, SHIFT_R, CTRL_L, CTRL_R,
* ALT_L or ALT_R.
*
* additionalFlags:
* aAdditionalFlags of nsIDOMWindowUtils.sendNativeMouseScrollEvent().
* See the document of nsIDOMWindowUtils for the detail of the values.
*
* onLineScrollEvent:
* Must be a function or null.
* If the value is a function, it will be called when DOMMouseScroll event
* is received by the synthesized event.
* If return true, the common checks are canceled.
*
* onPixelScrollEvent:
* Must be a function or null.
* If the value is a function, it will be called when MozMousePixelScroll
* event is received by the synthesized event.
* If return true, the common checks are canceled.
*
* expected:
* Must not be null and this must have:
* axis:
* kVAxis if the synthesized event causes vertical scroll. Otherwise,
* it causes horizontal scroll, kHAxis.
* lines:
* Integer value which is expected detail attribute value of
* DOMMouseScroll. If the event shouldn't be fired, must be 0.
* pixels:
* Integer value or a function which returns double value. The value is
* expected detail attribute value of MozMousePixelScroll.
* If the event shouldn't be fired, must be 0.
*
* Note that if both lines and pixels are 0, the test framework waits
* a few seconds. After that, go to next test.
*
* init:
* Must be a function or null. If this value is a function, it's called
* before synthesizing the native event.
*
* finish:
* Must be a function or null. If this value is a function, it's called
* after received all expected events or timeout if no events are expected.
