Don't compute vertex transformation on GPU side.

This patch is to avoid a regression introduced by commit:
commit 05ad89f91241b386f72f5b9bac3ebe62faff1d1b
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Sun Feb 3 16:51:35 2013 +0000

    gl: Replace manual vertex transformation with VS computation of texcoords

After fix that regression, we can revert this patch.
This patch can fix the rendering problem in IE Fish Tank Benchmark.
