The patch ended up more complicated than I anticipated due to a lot of places in webrender assuming texture arrays unless specified otherwise. The patch also merges TextureTarget into ImageBufferKind, and removes the realloc code path ing the texture cache (which is supposed to be dead code since because of performance issues on windows+intel).
