* minified). 1D and 1D array surfaces are stored effectively the same way,
* except that pitch never plays into it. All the levels are logically
* adjacent to each other on the X axis. The qpitch becomes the number of
* elements between array slices, while the pitch is unused.
*
* Each level's sizes are subject to the valign and halign settings of the
* surface. For compressed formats that swr is unaware of, we will use an
* appropriately-sized uncompressed format, and scale the widths/heights.
*
* This surface is stored inside res->swr. For depth/stencil textures,
* res->secondary will have an identically-laid-out but R8_UINT-formatted
* stencil tree. In the Z32F_S8 case, the primary surface still has 64-bpp
* texels, to simplify map/unmap logic which copies the stencil values
* in/out.
