Scaling "Stroke" Effect "Brush Size" while scaling composition? I've got a 100x100px composition with a Mask containing a Stroke effect used to animate the drawing of a vector. The problem I'm having is when I drop this composition into a larger one and attempt to scale it up, the Brush Size in Stroke remains the same (e.g. the graphic is drawn with thin lines, instead of the thicker looking ones in the smaller comp). 

I'm thinking some sort of expression magic might be the fix to this, but any input on how to maintain line thickness at any resolution/scale would be much appreciated. Thanks!

EDIT: I've attached a small demo project showing the issue I'm running into below:

Easy fix, you see the small sun icon on the imported comp layer? Disable that, that basically means that the comp should act like the layers within it should act like they are in the parent comp. It negates the transformation your are applying to it and the effect will just keep its pixel value its supposed to have, you are not "blowing it up" like you would expect.
If you disable it the imported comp will act like a rendered video.

If you have huge pixelation going on just go to full resolution in the preview and it will be fine, though the layer will not act like a vector, you will have a rasterized image so keep in mind to have a big enough resolution if you want to scale it up.
Better to have it bigger and scale it down than having not enough.
