Hi,
I think this patch and the following ones are fine, but I'd like to have my remaining copy propagation patches accepted before them, given that they have been in review for weeks and they are still waiting for reviewers' comments.
Unrelatedly, while reading this patch I noticed that hlsl_new_texture_type() allocates using vkd3d_calloc() instead of hlsl_alloc(). I guess that's an oversight, isn't it?
Giovanni.
