QWindowsDrag::defaultCursor() used xpm-based cursors which are aliased,
dark and not available in different sizes.
This patch uses the new cursors from QWindowsCursor::customCursor for
the drag cursors and gets the ignoreDragCursor from the system. If
fetching the ignoreDragCursor cursor fails, we still fall back to the
ignoreDragCursor.xpm.
The other xpms were moved to QWindowsDrag::defaultCursor() for the WinCE
or non-png case.
