Re: [PATCH 0/4] MR299: vkd3d-shader/hlsl: Get SM4 texture allocation order and RDEF bind count for lowered combined samplers right.

[Zebediah Figura (＠zfigura)]

Do we know that the rule in 4/4 is correct? Could it be, instead, that variables are sorted in descending order of bind count? IIRC the latter has some form of precedent; I think that's how numeric variables are sorted for sm1.

Also, from patch 4/4:

```
+                    list_remove(&var->extern_entry);
+                    list_add_after(insertion_point, &var->extern_entry);
+                    insertion_point = &var->extern_entry;
```

This works, but I think it might be slightly clearer to build a local list, append to its tail, and then list_move_head() to ctx->extern_vars.
