Theming Question

[Goldenwind]

Hey guys. I'm trying to do an advanced thing with themes.
Breaking the problem down...

I have a vertical line graphic. I change its length periodically using zoomy.

Now, there are actually multiple lines.
The first one, mentioned before, goes upwards, hence zoomy works.

The next one is actually at 72° (Assuming up is 0°).
The problem here is, I can't control the length of the second line, since zoom, zoomx and zoomy are applied after rotationz. I can make it the proper length, but it also makes the line very thick.

How can I have each of my lines the proper width, while getting their length to where it should be?

First line:
zoomy,1.9*Function()

Second line:
zoomx,math.cos(18)*2.7*Function();zoomy,-math.sin(18)*Function()*2.7;rotationz,72

The above make the lines the right length, but the second line gets thicker.
(The function returns a percentage that controls the length of the line, like a status bar)

How could I handle this?
