Bug ID: 53442
           Summary: Total War Shogun 2 needs D3DX_FILTER_BOX for memory
                    management.
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: d3d
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Total War Shogun 2 uses the D3DX_FILTER_BOX filter to downscale it's textures.
Both during normal usage, but more critically, when it's VRAM budget is low or
over-committed.

This can be seen on Intel GPUs in the game's stderr output with a line similar
to:
---snip---
** Downsizing Textures, Over Budget by : 115 Mb
---snip---

Followed by (in wine-7.12 or older) or prior (in wine-7.13 or later) multiple
fixmes:
---snip---
0024:fixme:d3dx:D3DXLoadSurfaceFromMemory Unhandled filter 0x5.
---snip---

See also the attached log from wine-7.13.

As this filter is used for memory management in a 32bit game, it's
implementation would help alleviate some OOM errors.
