Switch to glyphs as paths at a higher point size on Android

Browse Source 
The regression occurred when we dropped the maximum DF size from 192
to 162, which meant that any glyph > 324 ended up being rendered as paths
rather than the previous > 384. This pushes the threshold for
rendering paths up to 384. Quality looks fine on high-res devices
which is why this is restricted to Android-only (low-res Android devices
should only rarely have text that large).
