[Bf-codereview] Displace Node (issue 5528108)

[jbkkavt at gmail.com]

Dalai,

please check. Using you example file I couldn't reproduce it anymore. It
is a rounding issue with the +0.5f isplaced pixel in uv coords, for
image sampling

I tested with values from -100 to +100 for Xscale and Yscale.

Regards,
Jeroen
