ActionScript 2.0 :: Draw A Filled Rectangle With No Border?

I'm trying to draw a filled rectangle with no border. Here's the code for my test project:

ActionScript Code:
myMC = this.createEmptyMovieClip("", this.getNexthighestDepth()-1);
myMC._x = 0;

[Code].....

If you take a look at the coordinates, this was suppose to draw a 180x22. Well, it looks lika it draws a 180x22 rectangle, but only if the zoom is at 100%. If I zoom in on the flash player, there are two problems:

1) the line, as it is scaled, goes over the shape edge. Basically, as the border line has 1 pixel, Flash starts do draw it half pixel up and half pixel left; 2) the rectangle is in fact a 179x21 pixels, instead of the 180x22.

I'm sending an example project on an attachment. In this example I have 2 vertical rectangles which act as buttons:

1) the first button draws the rectangle step-by-step;
2) the second button cycles through 3 different styles:
2.1) line with 1 pixel, normal border rescale. This is the style at start;
2.2) no line;
2.3) line with 1 pixel, no border rescale.

The background is a checker texture, with 1 pixel per square. This gives you a perfect look on how the line is drawn.

The drawing instructions are executed on the yellow movieclip, which serves as reference, considering that it has the desired dimensions (180x22). *

If you zoom a couple of times you'll be able to see the problems I'm experiencing.

All you have to do is to click the first vertical button several times to draw the lines, to press the second vertical button to reset the draw and to change the border style, and finally to look at the draw with some zoom in, in order to see it in detail.

So, what can I do in order to draw a perfect rectangle, meaning that the border will not go outside the shape (it would be nice that when the border is rescaled, it does it inside the boundaries of the shape) and the rectangle has right dimensions (why am I missing one pixel in each direction?).

* By the way, is there a way to draw in a movieclip using the lineTo in such a way that the drawing is on the topside instead of the bottomside? I had to make the yellow rectangle partially transparent in order to see my drawing.
