Intermittently missing glyphs on Android on Adreno 3xx devices

This seems to happen often but not every time, not sure why. This was originally filed by kats as bug 1505508, observed on his Z3C (Adreno 330). On Adreno 4xx, 5xx and 6xx devices I noticed similar behaviour, and proceeded to investigate then fix that. That solution does not work for Adreno 3xx GPUs as they are missing the required extension. Additionally, the 3xx bug seems to have a slightly different cause, though I do believe it is also a driver bug when blitting between textures to resize the texture cache.
