<pre>Just pushed to master. I don't think Neil realized that Cody didn't have
commit access... and then everyone forgot about it.

i965: Require pixel alignment for GPU copy blit
The blitter will start at a pixel's natural alignment. For PBOs, if the
provided offset if not aligned, bits will get dropped.
This change adds offset alignment check for src and dst, kicking back if
the requirements are not met.
The change is based on following verbiage from BSPEC:
Color pixel sizes supported are 8, 16, and 32 bits per pixel (bpp).
All pixels are naturally aligned.
Found in the following locations:
page 35 of intel-gfx-prm-osrc-hsw-blitter.pdf
page 29 of ivb_ihd_os_vol1_part4.pdf
page 29 of snb_ihd_os_vol1_part5.pdf
This behavior was observed with Steam Big Picture rendering incorrect
icon colors. The fix has been tested on Ubuntu and SteamOS on Haswell.
