ActionScript 2.0 Language Reference - Adobe Help and Support

You might notice that two of these buttons, one in the main SWF file and one in the loaded
SWF file, have the same depth value. This is misleading because buttonMovie.swf was loaded
at depth 999, which means that the button it contains will also have a depth of 999 relative to
the buttons in the main SWF file. You should keep in mind that each movie clip has its own
internal z-order, which means that each movie clip has its own set of depth values. The two
buttons may have the same depth value, but the values only have meaning in relation to other
objects in the same z-order. In this case, the buttons have the same depth value, but the values
relate to different movie clips. For example, the depth value of the button in the main SWF
file relates to the z-order of the main timeline, while the depth value of the button in the
loaded SWF file relates to the internal z-order of the myClip_mc movie clip.

public _highquality : Number
Deprecated since Flash Player 7. This property was deprecated in favor of Button._quality.
Specifies the level of anti-aliasing applied to the current SWF file. Specify 2 (best quality) to
apply high quality with bitmap smoothing always on. Specify 1 (high quality) to apply antialiasing;
this smooths bitmaps if the SWF file does not contain animation and is the default
value. Specify 0 (low quality) to prevent anti-aliasing.
