Draw outlines using draw() commands, rather than a second SVG

[MewPurPur]

SVGs are really taxing on performance, so this should reduce the overhead of changing the SVG and zooming in/out by at least a little bit (probably by something like 40%).

This will also fix how these outlines aren't drawn outside the texture even if they stretch a little out.

Care should be taken to not draw a lot of lines out of bounds (like if you put x=999999 y=999999 as a curve end point in a path) as this might freeze the app if it's not done with care.
