Subject: svga: fix copying non-zero layers of 1D array textures
X-Git-Tag: upstream/17.1.0~10279
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=abc6432d54c4b4b50368f230634ed8a0d2c92e34;p=platform%2Fupstream%2Fmesa.git

svga: fix copying non-zero layers of 1D array textures

Like cube maps, we need to convert the z information to a layer index.
Also rename the *_face vars to *_face_layer to make things a little more
understandable.
