Path elements with transparent fills removed #27
Description
Hi, hope you're doing well! Thanks for all your work on SwiftDraw!
Just reaching out again about another issue we're running into - we noticed that elements with transparent fills are removed from the final output. For example, we have the following SVG:
Here are the relevant elements:

The first element is removed from the final output. I'm guessing this is an optimization with the idea that transparent elements wouldn't be visible in the final symbol, but we'd actually like to retain the layer since we want it to be dynamically recolorable. Is it possible to support this? Perhaps elements with classnames indicating they support recoloring should be preserved, even when their fill is transparent?
