* the "source crop" is rounded to texel boundaries.
* This can produce significantly different results when the texture
* is scaled by a large amount.
*
* The GL code below is more logical (imho), and the difference with
* HWC is due to a limitation of the HWC API to integers -- a question
* is suspend is whether we should ignore this problem or revert to
* GL composition when a buffer scaling is applied (maybe with some
* minimal value)? Or, we could make GL behave like HWC -- but this feel
* like more of a hack.
