[virglrenderer-devel] [PATCH] vrend: specify destination z in resource copy fallback path

[Gurchetan Singh]

We don't always start at a z-offset of zero. For example, when
Gallium copies a temporary depth texture to the final depth texture
[i.e, the one finalized in st_finalize_texture(..)], it sends the
copy commands one slice at a time.

Fixes:
dEQP-GLES3.functional.texture.specification.teximage3d_depth.depth_component32f_2d_array
dEQP-GLES3.functional.texture.specification.teximage3d_depth.depth_component24_2d_array
