This bug occurs because D3DX_FILTER_TRIANGLE is not implemented in
D3DXLoadSurfaceFromMemory.

Touhou (10 (MoF) or later) depend heavily on D3DX[1]. Wine's D3DX has a lot of
FIXME. So, Touhou (10 (MoF) or later) on Wine have some bugs.

Microsoft deprecated D3DX and created the successors (such as DirectXMath and
DirectXTex)[2]. The successors are licensed under the MIT License.

The patch[3] is based on DirectXMath and DirectXTex[2]. The patch handles
D3DX_FILTER_TRIANGLE in D3DXLoadSurfaceFromMemory.

The patch needs to be rewritten in C (currently, the patch is written in C++),
but I'm busy...
