Revert "Reduce the amount of padding needed for SDFs, take 2"

This reverts commit 10105308dc86dccd3d4a0c8b9863d7c749440b21.

Reason for revert:

Crashing in dm on Chromecast, looks like on dftext gm.
Seeing shape drop-outs in persp_shaders_bw on IntelBayTrail in gldft mode (second column, third and fourth rows).

Original change's description:
> Reduce the amount of padding needed for SDFs, take 2
> 
> 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 2, and outset the original bounds by one texel. This allows us
> to increase the maximum size in the atlas.
