Revert "Reduce the amount of padding needed for SDFs."
This reverts commit b42610aa9b0e431c5658f7f9ada8553e4f90869c.
Reason for revert: Seeing some corrupt text in certain GMs.
Original change's description:
> Reduce the amount of padding needed for SDFs.
>
> SDF glyphs and paths were padded by 4 pixels, and had an inset of 2
> pixels within that for rendering the shape. We should be able to
> use a pad of 1, and the original bounds for the shape. This allows us
> to increase the maximum size in the atlas.
